See if this EFI-v3 fixes the KP when OC hands over control to the installer.

Hey, new things happen again. The bootloader is fast again, i even have OpenCore set as my first boot option when i checked in my BIOS. Thanks for whatever you did! This time i was greeted with "The operation could not be completed. (com.apple.diskmanagement.disenter error -119930877.)", even quicker, i mean after the first restart. Right now im reading that this is a problem with macOS recognising your drive. Ill restart the whole installation. By the way, earlier you said i havent mapped my USBs correctly, why is that?
Edit: After a few tries i got to the same situation - apple screen, progress moving from 29 to 27 minutes and then the installer popping up with "An error occurred while preparing the software update.".
Edit again: Ive booted quite a few times and after the installer restarts around 5 times every time it freezes in random places. In the beginning it was freezing at the apple logo, now i cant even get past the verbose logs. For example the system straight up freezes in the middle of printing a path or i get no display output.
