zombie-fied on exit

[drmcnelson]

Describe the problem

After closing Arduino IDE, it is impossible to start it again. A long list of processes remains in the process list.

To reproduce

On Linux:

1. Start Arduino IDE.
2. Use the IDE for a while.
3. Close, using the X at the upper right corner of the IDE window.
4. Attempt to start Arduino IDE again. If it starts successfully, repeat the process until it fails to start.
5. Run the following command from the terminal:

   ps -ax | grep -i arduino
   

🐛 Processes that were spawned by Arduino IDE are still running:

Expected behavior

Closing Arduino IDE by any method, should result in a clean exit, reliably to a state from which it can be restarted.

Arduino IDE version

2.3.2

Operating system

Linux

Operating system version

Fedora 40, Cinnamon Desktop

Additional context

I am using the Appimage package.
