Big sur stage 2 installation fail

My laptop: Asus TUF FX705GM i7 8750H GTX 1060 (disabled using the boot argument) 1TB SSHD for booting OpenCore and then macos

I was previously using Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina and downloaded Big Sur update from the app store. I'm on OpenCore 0.6.3 and all my kexts are up to date. I installed Big Sur from Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina and when it restarts after installation, proceeds for second part of the installation after restart, I receive this error:
