Can't get to Big Sur installer

[jr_3000]

I am trying to upgrade my Catalina 10.15.7 to Big Sur, or even get a fresh install.
My system works fine with opencore 0.6.3. Everything seems to be working fine, audio, ethernet, video, etc.

My problem happens when I try the Install macOS Big Sur option in the USB. After a little bit it stops at the error shown below.

If anyone could have any ideas on how to solve this I really appreciate.

I am attaching a photo of the error and my EFI.

Thanks

My issues with Big Sur and stackshot error have been related to the IGPU and Whatevergreen. I was receiving them with my laptop and the only way to make it stop was to disable whatever green. Once I did that everything went well. Since you have a GTX680 you likely could just disable the IGPU if you have one.

thanks for the reply. I have tried disabling whatever green but the error is still there.
