If you have Elden Ring on PC, check out the seamless co-op mod. We were able to play through the whole game with very few issues. No invasions, no resummoning after bosses, normal use of torrent. It’s fantastic, and it’s shocking how well the mod works.
Look into installing AppArmor instead of SELinux. AppArmor is easier to configure, and SELinux is not officially supported on Arch.
