Summary

This article covers what to do when Microsoft Teams opens but displays a blank white screen, a perpetual loading spinner, or an empty window where chats and channels should be. These symptoms have different root causes than login loops or sign-in errors, and the fixes below address GPU rendering conflicts, corrupted cache data, and broken WebView2 components.

In this guide

• 1. Try the Teams Web App First
• 2. Restart Teams Fully
• 3. Clear the Teams Cache
• 4. Disable GPU Hardware Acceleration
• 5. Clear WebView2 Data
• 6. Repair or Reset Teams via Windows Settings
• 7. Reinstall Teams
• 8. When to Contact IT

Before You Start

• A Microsoft 365 account with a Teams license.
• An active internet connection (verify by opening a web page in your browser).
• Windows 10 or Windows 11.

Instructions

1. Try the Teams Web App First

Before troubleshooting the desktop app, confirm whether the issue is local to your computer or affects your account everywhere.

1. Open your browser and go to https://teams.microsoft.com.
2. Sign in with your work credentials.
3. If the web version loads normally, the problem is specific to the desktop app — continue with the steps below.
4. If the web version also shows a blank screen, the issue may be account-related or a service outage. Check https://status.office.com for known issues before proceeding.

2. Restart Teams Fully

Closing the Teams window does not always quit the app — it often continues running in the background. A full restart clears the running process.

1. Right-click the Teams icon in the system tray (bottom-right corner, near the clock).
2. Select Quit (or Close).
3. Press Ctrl + Shift + Esc to open Task Manager.
4. Look for any remaining Microsoft Teams processes in the list.
5. If you find one, click it and click End task.
6. Wait 10 seconds, then reopen Teams from the Start menu or taskbar.

3. Clear the Teams Cache

Corrupted cache files are the most common cause of blank screen issues. Clearing the cache forces Teams to rebuild its local data from the server.

1. Fully quit Teams using Step 2 (make sure no Teams process is running in Task Manager).
2. Press Win + R to open the Run dialog.
3. Type the path for your version of Teams and press Enter:
   • New Teams (Teams 2.x): %localappdata%\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams
   • Classic Teams: %appdata%\Microsoft\Teams
4. Select all files and folders inside this directory and delete them.
5. Reopen Teams. You will need to sign in again, and Teams will download fresh data.

4. Disable GPU Hardware Acceleration

Teams uses your computer's graphics hardware (GPU) to render its interface. On some systems — especially those with older or integrated graphics drivers — this causes the blank screen.

1. If Teams opens far enough to see the title bar, click the three-dot menu (⋯) next to your profile picture.
2. Select Settings > General (Classic Teams) or Settings > Appearance and accessibility (New Teams).
3. Find the option Disable GPU hardware acceleration (Classic Teams) or Use hardware acceleration when available (New Teams — toggle it off).
4. Close and reopen Teams.

If you cannot access Settings because the screen is blank, use this workaround for Classic Teams:

1. Fully quit Teams (Step 2).
2. Press Win + R, type %appdata%\Microsoft\Teams and press Enter.
3. Open the file desktop-config.json in Notepad.
4. Find "disableGpu":false and change it to "disableGpu":true.
5. Save the file and reopen Teams.

5. Clear WebView2 Data

New Teams (2.x) uses the Microsoft Edge WebView2 runtime to render its interface. Corrupted WebView2 data can cause blank screens even after clearing the Teams cache.

1. Fully quit Teams (Step 2).
2. Press Win + R, type the following path and press Enter: %localappdata%\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams\EBWebView
3. Delete all contents inside the EBWebView folder.
4. Reopen Teams.

6. Repair or Reset Teams via Windows Settings

Windows has built-in tools to repair or reset apps without uninstalling them.

1. Press Win + I to open Settings.
2. Navigate to Apps > Installed apps.
3. Find Microsoft Teams in the list and click the three-dot menu (⋯) next to it.
4. Select Advanced options.
5. Scroll down and try Repair first. This fixes common issues without removing your data.
6. If Repair does not fix the problem, click Reset. This clears all local Teams data (equivalent to a fresh install).
7. Open Teams and sign in again.

7. Reinstall Teams

If none of the above steps resolve the blank screen, a clean reinstall replaces all app files.

1. Press Win + I to open Settings.
2. Navigate to Apps > Installed apps.
3. Find Microsoft Teams, click the three-dot menu (⋯), and select Uninstall.
4. After uninstallation, clear any remaining cache files (see Step 3) to ensure a completely clean install. No messages or files live in the cache — they are on Microsoft's servers, and Teams downloads them again when you sign in.
5. Restart your computer.
6. Download the latest version from https://teams.microsoft.com/download and install it.
7. Sign in with your work credentials.

8. When to Contact IT

Tell the helpdesk one thing above all: whether Teams also shows a blank screen in the browser at https://teams.microsoft.com. That answers whether the problem is your computer or your account. Add the steps you already ran — cache clear, GPU acceleration off, repair, reinstall.

Contact your IT helpdesk if:

• You have completed all steps above and Teams still shows a blank screen.
• The Teams web app (https://teams.microsoft.com) also shows a blank or broken interface — this may indicate an account or licensing issue.
• You receive an error about Conditional Access or device compliance.
• Your organization uses a proxy server or firewall that may be blocking Teams network traffic.
• Multiple people in your office are experiencing the same blank screen at the same time — this may indicate a service outage or a network-level issue.

Troubleshooting

DANGER

A blank screen in Teams is almost always a local desktop app issue. If Teams works in the browser but not in the desktop app, the problem is on your computer — not your account. Start with clearing the cache (Step 3) and disabling GPU acceleration (Step 4), which together resolve the majority of blank screen cases.

Symptom / Error	Potential Cause	Solution
White screen immediately after opening	GPU hardware acceleration conflict	Disable GPU acceleration (Step 4).
Blank screen after Windows update	WebView2 runtime updated or corrupted	Clear WebView2 data (Step 5), then restart Teams.
Spinner that never stops	Corrupted Teams cache	Clear the Teams cache (Step 3).
Teams briefly shows content, then goes white	Cache partially corrupted	Clear cache (Step 3) and disable GPU acceleration (Step 4).
Blank screen only on one computer	Local app or driver issue	Repair or reset via Settings (Step 6). If that fails, reinstall (Step 7).
Blank screen on all devices (including web)	Account issue or service outage	Check https://status.office.com. If there is no outage, ask IT to confirm your Teams license is assigned and that no Conditional Access policy is blocking your sign-in.
"Something went wrong" with blank content area	WebView2 or cache corruption	Clear WebView2 data (Step 5), then clear Teams cache (Step 3).
