Hi, it looks hard. Put your mobo in the barre search and see if someone has same board as you.

Hi there.

This is still a GPU-related problem.

How did you create your OpenCore installer?

What does the pre-built DSDT do ?

If I was building a PC using your components I'd follow this Golden Build guide:

ASUS Prime Z490-A, Intel Core i9-10850K, 64GB RAM, RX 5700 XT GPU

Updates: 01/27/2021 Updated Files with a new GPU SSDT. Shiloh's Build for Tristan ASUS Prime Z490-A - Intel Core i9-10850K - CORSAIR Vengeance LPX 64GB - Sapphire Radeon Pulse RX 5700 XT Components: ASUS PRIME Z490-A LGA 1200 (Intel 10th Gen) Intel Z490 SATA 6Gb/s ATX Intel Motherboard...

Okay, graphics are different but booting will be the same.

well
i fix iGPU problem adding my old GPU MSI 8400GS and now I'm able to reach Catalina installer

but I get Russian language!!!

I already tried to set the prev-lana:kbd leaving blank <>... no way
I choose HEX and non HEX ... but no way

MAYBE I have the russian only catalina installer on the USB drive?? i don't know...

PS: OpenCore startup screen says WatchDog is 1... may be the the problem is due to that?
