New Teams crashes whenever I turn on a webcam in a meeting

Hi @Larsen, Tom,

Thank you for posting your question in the Microsoft Q&A forum. 

We truly regret the inconvenience you've encountered and greatly value the steps you've taken to resolve the issue.

Here're suggestions you can try to fix it:

1. Clear Teams cache

For Windows:

• If Teams is still running, right-click the Teams icon on the taskbar, and then select Quit. 
• Pressing Windows+R to open the Run dialog box. 
• In the Run dialog box, enter the following path, and then select OK. 

%userprofile%\appdata\local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams

• Delete all files and folders in the directory. 
• Restart Teams. 

For macOS:

• If Teams is still running, right-click the Teams icon in the dock, and then select Quit or press Command+Q. 
• In the Finder, open the /Applications/Utilities folder, and then double-click Terminal. 
• Enter the following commands, and press Return after each command: 

rm -rf ~/Library/Group Containers/UBF8T346G9.com.microsoft.teams

rm -rf ~/Library/Containers/com.microsoft.teams2

• Restart Teams. 

2.  Use camera diagnostic tools (for Windows)

• Go to Settings > System > Troubleshoot > Other troubleshooters
• Run Camera and Video Playback.

3. Submit feedback to Microsoft

While I understand this may not be the answer you were hoping for, I want to assure you that your feedback is truly valued. As community moderators, our role is to guide users to the right resources and support channels, though we don’t have direct influence over product design decisions or access to internal development timelines. 

That’s why your input is so important. The most effective way to make your voice heard is through Microsoft’s official feedback channel. The product team actively reviews customer suggestions to identify areas for improvement and prioritize future updates.  

To ensure your voice reaches the right team, I highly encourage you to submit your feedback directly through: 

1. Teams > Three dot (on the right top corner) > Feedback > Report a problem 

1. Or via the Microsoft 365 Feedback Hub: Go to Microsoft 365 Feedback Hub > Send Feedback > Describe your proposal in detail 

Sharing your experience through this channel is the most impactful way to advocate for a change that would benefit you and other users.   

Additionally, since many other users have expressed similar concerns but may not know where to submit feedback, if my response has helped you better understand the situation and guided you toward a possible next step, please mark it as the “Accepted Answer.” Your action will help pin this post to the top, making it easier for others in the community who are experiencing the same issue to find your feedback and support it.  

Thank you for your kindness and contributions to the forum.
