Opencore Catalina Panic Help

Opencore Catalina Panic Help

panic diag file unavailable, panic occurred prior to initialisation

Hi all, I'm new to hackintosh. I used Opencore 0.6.2 to install Catalina and worked fine for a week and I'm having trouble to get into OS. I need to use "Recovery" option to recover my SSD in order to boot into OS and after I shut down the OS same thing happened again.

I tried to google for a week but I couldn't think of where the problem would occur if I'm able to boot in with "recovering my hard drive"

I tried to switch a different EFI

I tried to recover different date from time machine

Looked through BIOS
