Yes, it remains in full-screen mode.
I have to add some more information (I will also edit the initial post message):
The host is running on Windows 11 (upgrade from Windows 10, no fresh installation) and my VM is running furthermore on Windows 10.
There was no hardware replacement
I attached the log file you have requested. It contains data from October 7.
I switched to two monitor layout at 04:22. The two monitor layout crashed at 04:38.
Thanks for your support.
