Problem running qbittorrentvpn

I have binhex/qbittorrentvpn running on zimaos. Did a docker pull, docker run and then migrated into zimaos. Runs fine until you enable VPN in settings. This problem is caused by containerd. It can be solved in 2 ways. 1 run sudo apt install containerd.io=1.7.23-1 to revert to older version, or 2 add devices /dev/net/tun:/dev/net/tun in settings file. I cant apt install and have no idea where zimaos hides /dev/net/tun. Any help appreciated.

thanks
