I am having kernel panics in Big Sur 20A5343i and the panic log is indicating involvement with Soundflower and an old Blackmagic Framebuffer kext.
The problem is that while I've deleted these kexts from /Library/Extensions, they are still getting loaded.
I found them also in /Library/StagedExtensions/Library/Extensions/ and removed them from there as well.
But still, they are getting loaded.
I think they are in a cache, but kmutil won't update the boot cache:
Has anyone found how to update the kext cache in the boot kernel collection in Big Sur?

Has anyone found how to update the kext cache in the boot kernel collection in Big Sur?
