Avast lacks permissions

I uninstalled my old security solution and installed Avast on my MacBook Pro (Retina, 15-inch, Mid 2015). Avast wouldn’t work with my OS so I updated to MacOS Monterey 12.0.1

The frist time I booted with the new OS it asked me to grant permissions, which I did. I then rebooted and Avast 21.2 tells me that it is missing permissions. I click the “See How” button and nothing happens.

Avast has full disk access. I have rebooted, run a scan, searched Avast’s FAQs.

Any ideas before I go to an alternate solution?
