When shutting down my Mac, it takes 1-3 minutes to shutdown. The screen goes black for a few seconds, then the kernel panic message appears. I'm using a 2017 27-inch iMac, with macOS Big Sur 11.1. This did not happen immediately after upgrading to 11.1.
Edit This issue does not occur when booting in Safe Mode and shutting down from login screen without logging in.
Edit 2: This issue also does not occur with a new user account. Kexts are loaded in the user account, meaning the kernel panic does not occur from the kexts.
