Closing the programm with `Alt + F4` or `X` doesn't end the process

[reneas]

Describe the bug When closing the program it still shows in systemmonitor and it still drains resources. Even after waiting some minutes. This effect can stack, meaning there can be mutliple running instances of Fusion that take up the whole RAM of the system.

To Reproduce Steps to reproduce the behavior:

1. Start Fusion 360
2. Close Fusion 360 with Alt + F4 or clicking the X in the top bar
3. Check Systemmonitor
4. See Fusion process still running

Expected behavior

1. Start Fusion 360
2. Close Fusion 360 with Alt + F4 or clicking the X in the top bar
3. Check Systemmonitor
4. No Fusion process shown
