Keep getting Kernel panics(Reboots instead of shutdown)

[Maclife80]

Hey there,

I am running the latest Big Sur version but had this issue also before.
Currently what happens is that I want to shutdown my iMac. The computer shutdown gets black and then I get the black screen with white text saying your computer was restarted because of an error. Then he reboots normally and I get the error code in Mac OS Your computer was restarted because of an error with this report. Any clue what it is happening ????
