Windows 11 - KB5031455 (2023-10 Cumulative Update Preview) boots to recovery mode

Anyone else run into this? Windows 11 Pro/64 on latest proxmox, installing the above update, the VM boots into windows recovery mode, none of the repair options seem to work.

Restore from backup and tested several times - installing KB5031455 causes this everytime.

Have latest Virtio (240) installed. Using VirtIO SCSI
had the same error using host CPU type. I just switched to KVM64 to give it a try and the update went through. Not entirely sure this is indeed a fix as it could be sheer luck but maybe give it a shot?

(switching back to host CPU causes BSOD after the update)
