Update:
Reinstall 2023.04.06, then install latest intel GPU driver in Windows 10 guest. The installation failed. But the SR-IOV gpu works after reboot.

unraid 6.11.5
Tested the 1st version in plugin store.
After updated to 2023.04.06, windows guest gpu got error code 43.
Tried rollback to 2023.04.01, it's still code 43.
