Cant upgrade to Ventura from 12.6.3, gets 99% installed then black screen

[capy10]

Im having issues with the Ventura update as well. I am running iMac 20.2 ,using your latest opencore 0.8.9 it seems that the Updater installs up until the Apple sign it as it goes to almost 99% of the line it goes black and resets.
Should I turn off the internal GPU in bios? I am using imac 20.2 because i use sidecar. i have been using the SSDT for USB and deleted the original usb map as instructed. what am i doing wrong ?
Im posting my efi .. thank you in advance .. i have the same exact system as you except i am using a vega 64 card.
EFI 3.zip

and thank you for all your work on this project ... your the reason i bought the z490 Vision D and the i9-10900k
