My team's app occasionally displays an error, preventing me from opening it and attending meetings.Please give me a solution to this.Error is attached below.

Thank you, Benoit - that's helpful - good to know it should at least be fixed next week. A quick 'Quit Teams' from the system tray, and then re-opening does fix the issue for me long enough to join my next call. I usually have to do this 3-5 times a day on the days I have the issue, but between that and using Web Teams, I can get by......

I'm in the same situation, it started appearing for some users in my organization. Has anyone solved it somehow?

No, My research leads me to an issue related to the KB5048652 update installed on December 23, 2024 and including an update for WebView2...
WebView2 version after this update is 131.0.2903.112

After repair WebView2 I now have the version 131.0.2903.146

For repair WebView2 : (Doesn't work for me)

1. Add WebView2 Runtime to the list of programs.
   • Open Registry Editor.
   • Under [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Microsoft EdgeWebView] change the value of SystemComponent to 0.
2. From the Start Menu, open Add or remove programs under Control Panel.
3. Search for Microsoft Edge WebView2 Runtime.
4. Click on the three dots and select Modify then Yes in the popup.

   5. Click **Repair**.

Hello,

I also have the same problem systematically with an outgoing Teams call to someone in my organization.
As soon as I close the call I can no longer open a conversation by single-clicking, and the following error message appears with a double-click,

[UnknownError][Error:Cannot read properties of undefined (reading 'baseimageUrl')]Slot name:UNKNOWNWindows 10 22H2 (build 19045.5247)

The problem appeared on Friday, January 3rd...

I'm also getting the same problem. In addition, when receiving error " We've run into an issue", I noticed that none of the menu options on the side panel are working at all.

I have done everything you suggest, but the problem persists.
