Z490 USB Install - System doesn't have bridgeOS and doesn't support TRBX

I try to install Catalina on my Z490 using MacPro 7,1 using a OpenCore 0.8.5 USB Stick. The USB Stick is 32 GB, I reduced the partition to 20 GB.

The Installer loads, shows the first Apple Logo, Screen turns grey and the again the Apple Logo. After the Apple Logo the screen turns grey again and it shows me an error log file.

I can't get around this error and I don't know what it means at all.

Please see attached config.plist and error message.

Any idea?

Any idea? Strange thing is, when I use the EFI folder from here: https://github.com/ankanpratik/Gigabyte-Z490-AORUS-Pro-AX-EFI-OpenCore I get the same error. There I enabled the onboard graphic and Specs to iMacPro, same result.

It looks like that is related to this error message:
