Compressor not functioning since update

Greetings Higher Minds!

Ever since updating Compressor 4.6 (actually...the version previous had this issue too) I've been unable to get Compressor to function. I keep getting "unable to add to que". I've check Region and Language, Full Disk Access. I've trashed and reinstalled Compressor. I've disconnected all external devices and drives.

macOS Monterey. 12.0.1

Mac Mini (M1, 2020)

I'm able to export the desired file via Final Cut Pro. However, Compressor doesn't work when I export to it from FCP or drag and drop.

Any ideas?

Thanks in advance!
