FLT service won't restart after latest Debian Buster updates

Running PiHole on Debian Buster 5.10.63-v7+ on a raspberry pi3. Running latest PiHole version.

When I updated Debian Buster through the standard "sudo apt-get" command line I cannot get FTL service to restart via the typical commands.

Expected Behaviour:

I have been running PiHole for over a year now with very little headaches. First time not able to restart FTL service using typical command line with this most recent Buster update. Guessing something broke in root from output of FTL service status.

FTL service status output:

Actual Behaviour:
