5 minute delay

I’ve noticed a strange thing when trying to follow the qubes-tunnel guide on debian-12 template
After installing qubes-tunnel (by force via deb package!) it takes 5 minutes to start terminal first time
Can this have some connection to iptables or is it because my vpn doesn’t work?

btw
It would be nice to have a ready vpn template to download if vpn is important from a security perspective
