I have tested this with Earth Defense Force 5, and Dark Souls 3.
Closing out all instances of these games through the game itself will cause nucleus coop to silently crash. Using Ctrl + D to stop nucleus will sometimes also cause this crash, but closing out the games manually does every time.
Version info:
Dark Souls 3: latest
ds3os build v0.18.0.0-main
EDF5: latest
