I'm having trouble with the steps to add a Proton log--I added the launch option.

Splinter Cell: Chaos Theory used to work a while ago, but now the game won't launch. No error message is displayed--I click "Play", and after a moment, the button goes back to "Play". Even going through the Steam Library, as opposed to a launcher I created, the game doesn't run.

Hello @a1872, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/721#issuecomment-4422948219.
