Teamspeak blank screen at start

Hi everyone, I have a problem with my teamspeak : I have a blank screen (white when starting or invisible, then black when I move it around or resize it) where I can still click stuff. It was working perfectly before, I tried to log in today and doesnt work. I didn’t change anything and I started having this issue. I did my windows updates as well and it didn’t change anything as well as reinstalling it.
If anyone has a clue…
Thanks !
