Hello
Thank you for posting in Microsoft Community forum.
I apologize for the inconvenience you and your users are experiencing. I understand that this issue can be frustrating, and I will do my best to assist you.
Regarding the white screen issue, Microsoft is aware of this issue and is actively working on a fix. In the meantime, there are a few things you can try to mitigate the issue.
First, you can try disabling the "Use hardware graphics acceleration if available" option in Microsoft Teams. To do this, open Teams, click on your profile picture, select "Settings," and then navigate to the "General" tab.
Another workaround is to disable the "Use legacy console" option in Command Prompt. To do this, right-click on the Command Prompt icon and select "Properties." Then, navigate to the "Options" tab and uncheck the "Use legacy console" option.
I understand that these are not permanent solutions, but they may help alleviate the issue until a permanent fix is released. I hope this information helps, and please let me know if you have any further questions or concerns.
Best Regards,
Zack Lu
