WindowServer crash after Tahoe update - M4 Mac mini shows error on every startup

After updating to Tahoe, my M4 Mac mini (base model) shows a “WindowServer encountered a problem” warning on every startup.


The system works normally afterward, but this crash report appears automatically each time the device reboots.

This issue started only after the Tahoe update. I never saw this warning or crash before.


Is anyone else experiencing this issue? Could Apple engineers help with this problem?

Thanks.
