Ubuntu 24.04.2 LTS - Workaround

[mfrederico]

$ mkdir Exiled-Exchange
$ cd Exiled-Exchange
$ chmod +x /path/to/Exiled-Exchange-2-0.9.4.AppImage
$ /path/to/Exiled-Exchange-2-0.9.4.AppImage --appimage-extract
$ sudo chown root:root chrome-sandbox;  
$ sudo chmod 4755 chrome-sandbox

And that should get it working.
