Catalina to macOS Big Sur

Hi,
Finally, after three years I'm updating my Catalina to Big Sur on the Main system.
I use Clover 5141. Sorted out config and quirks. All fresh kexts.
Everything went well until the final stage.
Get stuck on Apple logo, which appears anyway even with -v enabled.
Graphics: GeForce GT 730
Any suggestions are appreciated. Thanks
