Teams Crashes or Freezes When Turning On Camera

Microsoft Teams relies heavily on camera drivers, hardware acceleration, and system permissions to enable video calls. When Teams crashes, freezes, or becomes unresponsive immediately after turning on the camera, the issue is usually related to graphics drivers, webcam drivers, hardware acceleration conflicts, corrupted app cache, or camera privacy settings.

This problem is common after Windows updates, driver updates, or when multiple applications attempt to access the webcam simultaneously. In most cases, the camera itself is not faulty. Instead, the crash occurs because Teams cannot properly initialize video hardware or conflicts with system resources.

Fixing Teams crashes or freezes when turning on the camera involves checking permissions, updating drivers, clearing cache, adjusting hardware acceleration, and repairing the app installation. Follow the detailed steps below to resolve the issue.

How to Fix Teams Crashes or Freezes When Turning On Camera

Go through each method carefully and test your camera in Teams after completing each step.

1. Restart Teams and End Background Processes

Temporary glitches can cause Teams to crash during video initialization.

1. Close Microsoft Teams completely.
2. Open Task Manager.
3. End all Teams-related processes.
4. Restart Windows 11.
5. Open Teams and test the camera again.

This clears stuck background services.

2. Check Camera Permissions in Windows

Windows may block Teams from accessing the webcam.

1. Open Settings.
2. Go to Privacy & security.
3. Select Camera.
4. Turn on Camera access.
5. Enable access for Desktop apps.
6. Ensure Microsoft Teams is allowed.

Without proper permissions, Teams may freeze when activating video.

3. Close Other Apps Using the Camera

Only one application can fully control the camera at a time.

1. Close apps such as Zoom, Skype, OBS, or browser tabs using the camera.
2. Restart Teams.
3. Turn on the camera during a test call.

Conflicts between apps often cause crashes.

4. Update Webcam Drivers

Outdated camera drivers can cause instability.

1. Press Windows + X.
2. Open Device Manager.
3. Expand Cameras.
4. Right-click your webcam.
5. Select Update driver.
6. Restart Windows after updating.

Updated drivers improve compatibility with Teams.

5. Update Graphics Drivers

Teams uses GPU acceleration for video processing.

1. Open Device Manager.
2. Expand Display adapters.
3. Right-click your graphics card.
4. Select Update driver.
5. Restart the PC after updating.

Graphics driver conflicts are a common cause of freezing.

6. Disable Hardware Acceleration in Teams

Hardware acceleration can cause video crashes.

1. Open Teams.
2. Click your profile picture.
3. Select Settings.
4. Go to General.
5. Turn off Hardware acceleration.
6. Restart Teams.

Disabling acceleration often resolves camera-related crashes.

7. Clear Teams Cache

Corrupted cache files may cause freezing.

1. Close Teams completely.
2. Press Windows + R.
3. Type %appdata%\Microsoft\Teams and press Enter.
4. Delete contents of the folder.
5. Restart Windows.
6. Launch Teams again.

Fresh cache files will be created automatically.

8. Repair or Reset Teams

If cache clearing does not work, repair the app.

1. Open Settings.
2. Go to Apps > Installed apps.
3. Locate Microsoft Teams.
4. Click Advanced options.
5. Select Repair.
6. If needed, select Reset.
7. Restart Windows and test the camera.

This fixes corrupted app components.

9. Disable Background Apps

Background processes may consume system resources.

1. Open Settings.
2. Go to Apps.
3. Select unnecessary apps.
4. Set background permissions to Never.
5. Restart the PC.

Freeing system resources improves video stability.

10. Check Windows Update

System bugs may affect camera functionality.

1. Open Settings.
2. Go to Windows Update.
3. Click Check for updates.
4. Install available updates.
5. Restart the system.

Updates often fix camera and app stability issues.

11. Test Camera in Another App

Confirm whether the issue is Teams-specific.

1. Open the Windows Camera app.
2. Turn on the webcam.
3. Check if video works smoothly.

If the camera crashes here as well, the issue may be driver-related.

12. Reinstall Microsoft Teams

If all else fails, reinstall Teams.

1. Open Settings.
2. Go to Apps > Installed apps.
3. Uninstall Microsoft Teams.
4. Restart Windows 11.
5. Download and install the latest version.
6. Sign in and test the camera.

A clean installation resolves persistent corruption.

Final Thoughts

Teams crashing or freezing when turning on the camera is usually caused by driver conflicts, hardware acceleration issues, corrupted cache, or permission settings rather than a faulty webcam. In most cases, updating drivers or disabling hardware acceleration resolves the problem quickly.
