AppImage fails to launch because it can't run things as root

[seebs]

Describe the bug

If I try to run the plover 5.2.0 AppImage on my Ubuntu 22.04 system, I get:

==== AUTHENTICATING FOR org.freedesktop.policykit.exec ===
Authentication is needed to run `/usr/bin/bash' as the super user
Authenticating as: seebs,,, (seebs)
Password: 
polkit-agent-helper-1: error response to PolicyKit daemon: GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: No session for cookie
==== AUTHENTICATION FAILED ===
Error executing command as another user: Not authorized

This incident has been reported.

This appears to be related to #1783, but is subtly different in that it just fully prevents loading. I've tried the suggested workaround of adding the group manually, etc, but I still get this.

It might be related to: polkit-org/polkit#18

To Reproduce

Run the AppImage on an affected system. Not sure what systems those would be exactly.

Expected behavior

Plover runs.

Operating system

• OS: Ubuntu 22.04
• Plover Version: 5.2.0

Hardware

N/A

plover 4 ran fine on this machine, a while back, but I don't have it installed right now to check.
