os15.5 install pendrive does not boot

Hi,

Please help.

I have a perfectly working 13.7 hackintosh on AMD Ryzen 3900x, RX580 4GB.

Need to update to 15.5.

I created a boot instalation pen with os15.5. EFI with config.plist as specified in Dortania, all kexts and drivers in proper catalogues.

When I choose the install pen in opencore I get stuck in apple logo screen. Even though I have -v in boot-args I see no verbose mode and I get no log.

I usa a DEBUG 1.05 open core.

What am I doing wrong, please help.
