I has been several days now I'm getting a blank screen when I try lo launch Teams.
Looking for solution around, the only one that actually worked for me is to resize the window. It seems an electron issue on rendering the page.
This is not as much a bug report, as a feedback on something you should fix.

Does anyone else have the same issue in your organization?
Are there any error messages when the black screen start up?
To exclude the client issue, we firstly recommend you try to login Teams web client to see if this issue can be reproduced. If there is no issue in Teams, you could try to clear your Teams client cache file by following these commands:
rm -rf ~/.config/Microsoft/Microsoft\ Teams.

I've seen the same thing for a long time. It happens very rarely when I'm using X11 (gives a white window), but occurs super often when using Wayland (gives a black window). I've seen the X11 white window on two different systems - no other app (even other electron-wrapped apps) on these systems ever has this problem.
I was just now testing with Wayland and it opened correctly on the first time, then gave me the black window 6 consecutive restarts after that. Resizing the window is the only thing that gets it to redraw properly. It's as if there's no update happening after the app initially writes to the surface/canvas. The app works fine other than this weird startup behavior.
Edit: Others appear to see it as well -

Apparently clearing the cache may fix it temporarily, but the issue will return. That almost sounds like a race condition.
