The bug affected me too. First reboot after updating the kernel. HP Pavilion 15(AMD Ryzen 5 4600H + nvidia 1650ti), after a restart the output from Nvidia is replaced by noise: https://www.youtube.com/watch?v=GAbUaWYDVEQ
Under it the system works, I can blindly log, run a terminal and, for example, reboot the machine.
I can switch between amd and nvidia GPUs with prime-select nvidia/intel ("intel" seems to mean "integrated" there), the AMD GPU works well.
If I can be helpful and provide more information, please tell me how.
