What version of teams do you have? What version per user ?
You can have a different versions per user??? Wanna go crazy this is how you go crazy.
Thankfully there is this guy: https://github.com/uclobby/Get-TeamsVersion
https://uclobby.com/2018/09/04/teams-check-client-version-using-powershell/

He saved my day. Unfortunately simplehelp doesn’t like the dashes he used.
So here it is again with the dashes fixed:
