Thanks for reporting the issue. This could be due to error in updating WebView2 Runtime. Can you try reinstalling the runtime manually from the installation site.

Hi, experience also this bug on an ARM Surface. Tried all troubleshooting steps like repair/uninstall. Install WebView2 Runtime etc.
Also an issue with GlobalProtect from PaloAlto. Temp resolved with using this Teams version and this GP version:

Teams/App error WebView2 not insalled

GP Arm version:
GlobalProtectARM64-6.0.7

At our end we have tried to uninstall/install again manually.
After that when opening teams/outlook it again says : "Please install webview"
on clicking install,  we get the message : "It is aleady installed"
.
After downgrading to : 131.0.2903.99 , which was already present in the machine in the folder :
"C:\Program Files (x86)\Microsoft\EdgeWebView\Application"
It has now started working,

confirming the problem with version : 131.0.2903.112
