No internet connection via piVPN after pihole-update 6

Beloved pihole-community, I am asking you for help,

Actual Behaviour:

When connecting to my home network via pivpn I can access the NAS, but I cannot use the internet.

setup: raspi 3B, Pi OS 10 (I should probably update, but I would like to do it a little later when I got more time to throw myself into the project of potential trouble)

Debug Token:

Thanks in advance!
