[SOLVED] Ventrua on Proxmox with GPU passthrough, Couldn't alloc class "AppleKeyStoreTest"

[adamgoodapp]

I'm trying to run Ventura on Proxmox with GPU passthrough.

CPU - AMD Ryzen 7950x

GPU - ASRock Challenger RX 6600

I first setup Ventura following Nick Sherlock's guide and had it working fine before GPU passthrough. Was able to access Ventura via console with no problems.

Then I followed guides to get GPU passthrough working, able to view Opencore and select Mac to boot but presented with the error in the picture.

The EFI folder is the same as v20 here

Solved by adding "agdpmod=pikera" to boot-args in OpenCore config.plist.
