Bug Description:

When trying to open several single instances of Theia AppImage or Snap app (Ubuntu 24.04), only the first instance opens the given workspace.

Steps to Reproduce:

1. Open Theia with a workspace path as command line parameter
2. Theia opens with given workspace loaded
3. Open a second instance of Theia with a path of another workspace as command line parameter
4. Theia opens without any workspace loaded

I didn't build Theia myself. I tried this with the downloadable AppImage and also with the snap package for Ubuntu 24.04.

Additional Information

• Operating System: Ubuntu 24.04 (Gnome)
• Theia Version: 1.57.1
