What happened?

Did work before the upgrade, no longer works after the upgrade.

Also tried a clean/fresh installation of Windows 11 Enterprise. Installation works, booting the VM works, installing Guest Additions works and 3D Support works too, until i reboot.

Once the machine is shutdown, it is no longer possible to boot it up, it just crashes as soon it is logging me in. I can see on the login screen, that 3D already works, transparency is there, but as soon he tries to switch the resolution, the crash happens.

For verification i tested with my 24H2 Machine and that one boots just fine and works. 3D works too. It seems to only affect the 25H2

How can we reproduce this?

Create a new Windows 11 VM with enabled 3D acceleration
Install Windows 11 Enterprise
Install Guest Additions
Reboot
