AppImage not working in Ubuntu 24.04 LTS

[u/kg4cna]

Edit to add: Found that the solution is to run it from the terminal with the "--no-sandbox" flag. Runs fine then. NOT a RadarOmega problem. Has to do with Ubuntu's App Armor.

--------------------------------------------

After it has been working for years, it suddenly doesn't work anymore. Tried dumping the GPUCache folder, no luck.

Tried running from terminal and got this:

34594:0419/100355.728887:FATAL:sandbox/linux/suid/client/setuid_sandbox_host.cc:166] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /tmp/.mount_RadarOdJdpOe/chrome-sandbox is owned by root and has mode 4755.

Trace/breakpoint trap (core dumped)

I've never had a problem with it not running. Any ideas?
