Unable to Reinstall MS Teams (Desktop)

I am unable to completely uninstall and reinstall teams. I am the admin user on this laptop (personal)

There are no running services, or program that I can uninstall/stop. But I am also unable to delete the one single file called 'Update' in Microsoft --> Teams folder.

This is the error message I get on the log, Any help to get around this much appreciated.
