Hello,

I had the same problem recently and I want to share what I have done to solve that, maybe it will be helpful.

 

1- Right click on the MS Team app -> properties -> "compatibility" tab -> "compatibility mode" section -> Tick the "Run this program in compatibility mode for" -> windows 7 -> Apply -> Ok

2- Right click on the MS Team app -> Run as administrator -> close it (without sign in)

3- Right click on the MS Team app -> properties -> "compatibility" tab -> "compatibility mode" section -> Remove tick the "Run this program in compatibility mode for" -> Apply -> Ok

4- Open the MS Team app and sign in.
