bwrap: Permission Denied

this is not a heroic issue, something wrong on your system

Ubuntu 24.04 : received the following error:
"[cli] INFO: Launching [key# omitted]..."
"pressure-vessel-wrap[11882]: E: Child process exited with code 1: bwrap: setting up uid map: Permission denied."
I have been told to check the /etc/subuid & /etc/subgid files to ensure both have:
[username]:100000:65536 , which both do.
Next, I was told to install uidmap, then log out & back in. I have also restarted since doing this, and my problem still exists.
The next step I wasn't sure about, so I came here for verification:
"Ubuntu 24.04 uses AppArmor, which may be blocking bwrap", referring to the permission fault. "Create a file, apparmor.d/[gamename], containing the following:
/usr/bin/bwrap {
/[game path]/** rm->,
/[game path]/** rw->,
}
and restart AppArmor: sudo apparmor_parser -r /etc/apparmor.d/[yourgame]"

Any explanation of what this might do, or if any of this is incorrect, would be welcome. Thanks!

I'd be happier if there was a single solution for the program, rather than each individual game.

Are you using the snap ?

[ObiWanPEZ]

I am not, but did open / reinstall the new version, when it ceased to work.

[Etaash-mathamsetty]

apparmor shouldn't be involved here at all unless something fishy is happening (like using the snap)
