I have had two users now that get this error message when trying to open Teams. We have had teams installed on our machines for over a year now, and within the same month both users have experienced this issue.
I have fixed it for both users temporarily by completely uninstalling Office 365 and reinstalling. But for one user the issue has reappeared, so obviously that isn't the correct answer. What's really strange is if the user clicks on a Teams link in an email or tries to open Teams through the system tray it opens just fine, but if he tries to open it normally from the start menu, a desktop icon, or from the taskbar he gets the error.
I'm not sure what else to do. User is on Windows 10 64 bit running the 64 bit version of Teams.

I had the same issue after checking for and installing a Teams update. It seems like the update uninstalled Teams but left the shortcuts. Go to Add/Remove programs ( or run appwiz.cpl) and uninstall Teams, then download it and reinstall.

This is plaguing my org at the moment as well. My ServiceDesk has had like 10 calls just this morning for staff that are experiencing this issue.
A re-install of the software resolves it but I'm nowhere near finding a root cause. And doing that for hundreds of staff every day is not feasible.
One thing I have noticed, on the affected machines:
C:\Users\%user%\AppData\Local\Microsoft\Teams\Update.exe file size is 0Kb while in this broken state.
Did you get any closer to a resolution?

One of our team members found this link and it worked for us, and fixed the exact same issue.
