Upgraded Catalina to BigSur successfully

I upgraded MacOS Catalina to BigSur via USB. I am on AMD and audio input does not work as usual. I am also getting "Memory modules misconfigured" message and hope to fix it later.

CPU - AMD Ryzen 5 3600

GPU - NVIDIA GT710

MOBO - MSI MPG B550 Gaming plus

RAM - Corair 16GB
