What's the problem 🤔

The issue described here: https://github.com/qdm12/gluetun/wiki/TUN-device-errors#cannot-create-tun-device-file-node-file-exists
But the fixes here: #884 didn't fix it, it appears the be the same issue that @trentwiles is having. The logs are attached.
And here is ls -l /dev/net on my host machine:

crw-rw-rw- 1 root root 10, 200 Apr 20 23:34 tun

I'm running docker compose as sudo, I also tried as the root user, but the both fail the the same above logs
