KP - Install 10.5.7 - USB - Z490

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?
