Qnap LXD Container with Pihole not working after update

Help
1

Expected Behaviour:

-operating system Ubuntu Kinetic on LXD Container
-hardware]_ Qnap TS-230

Actual Behaviour:

Pihole was running fine until 2 days before that I updated to the latest version. DNS service not running and FTL is down. I made a clean installation of Ubuntu and Debian also and the problem is still exists. I have an old LXC Container with Ubuntu 18 (so I can't update) with older versions of pihole and is running fine. Today I updated to the version that released today and the problem still exists.

Noone has an idea why latest version of FTL is not running?

Can I install an older version of FTL (before 5.20)?

Same problem.
There are several threads about this issue already. You can run pihole-FTL as root - see here: DNS service not running
Also looking forward to an update or reverting the last version.
