    MojtabaBabaei Hi - I had exactly the same issue. was driving me NUTS. Mine was working perfectly - and then just stopped. It coincided with a Microsoft update - so coincidence? I tried everything from a new MAC OS update, deleting and reinstalling teams; deleting my library files. 

     

    This silly thing worked or me: the app was open and I right clicked on the icon in my finder dock. I clicked sign out. I then closed the app and restarted. After logging back in, the whole app refreshed and it seems to be back and working.

I wrote about this a bit on my website: https://keithblack.ca/fixing-microsoft-teams-blank-interface-in-macos-vm/

For anybody who is looking at this post in 2023 and beyond... if you are running macOS in a VM (maybe to test new Teams admin stuff without testing directly on your machine), and have the same white screen issue, know that I was able to fix it by installing Teams on a physical machine, disabling GPU acceleration, then copying the setting files over to the VM.

Here's a little step by step:

 

  1. Install Teams on a physical machine
  2. Log into Teams, then go into Settings (within Teams) and disable GPU acceleration.
  3. Close Teams
  4. Go into ~/Library/Application Support/Microsoft/Teams and grab these 3 files (fair warning I don't actually know what one matters, I just copied over everything that seemed setting related):
    1. desktop-config.json
    2. Preferences
    3. settings.json
  5. Copy these 3 files into the same path, but this time on your VM
  6. Open Teams on your VM, and everything should be fixed (or at least it was for me). It even suggested logging in with the same user that the physical Mac was logged into)

That's what it took for my machine, and now it's working great. Back to testing!

    Absolutely brilliant, I've been struggling with this too and whilst I understand that people often re-install, it's not addressing the root cause.  My VM was a fresh build and I only created it because of this issue on another VM that I hadn't used for a while and didn't realise it was a preexisting condition so to speak.  

     

    As a bit of further info, the reason that I needed to log into teams on my Mac first was because you can't get to the settings if you aren't signed in and therefore can't disable GPU acceleration. 

     

    My machine specs are:

    2019 iMac 27 Core i5 

    OS Ventura 13.5.2

    Parallels Desktop VM is as above also
