Known issues:

I have followed the guide at https://dortania.github.io/OpenCore-Install-Guide
At the step https://dortania.github.io/OpenCore-Install-Guide/AMD/zen.html#nvram;

npci=0x2000This disables some PCI debugging related to kIOPCIConfiguratorPFM64, alternative is npci= 0x3000 which disables debugging related to gIOPCITunnelledKey in addition. Required for when getting stuck on PCI Start Configuration as there are IRQ conflicts relating to your PCI lanes. Not needed if Above4GDecoding is enabled. Source
The OpenCore could not boot with "Above4GDecoding" enabled with or without additional boot arg "npci=0x2000"; I had to disable "Above4GDecoding" and add "npci=0x2000" to boot-args
