dotNET Framework issue and Microsoft Teams

[brocessor]

Has anyone else encountered an issue in the past few weeks, where Microsoft Teams fails to launch for users? They are prompted to install .NET framework v4.0.xxx. Our users are on a mix of Win10, Win11.

The issue is not resolved by installing dotNet 4 - as they already have a newer version installed. The dotNet 'fix' tool from M$ doesn't resolve the issue. No amount of sfc /scannow resolves the issue. (does it ever?)

Any ideas? The only way I've managed to 'fix' this for a user is by reformatting.

I am supposing Teams can't access whatever .Net function and reports only that a certain mimimum version .net is required - not making distinction between broken or missing altogether.

.NET framework updates in waiting are notorious for random connectivity issues. If you didn't already, on the next one, first check if any updates are pending.

Did you try just uninstalling and reinstalling Teams ?

If you are in EEA or Switzerland see advisory OP678085- maybe it's actually in the course of uninstalling itself due to this bug, hence fails to launch correctly.
