Please describe your issue in as much detail as possible:

Describe what you expected should happen and what did happen. Please link any large code pastes as a Github Gist:

Launching BPM from either streaming (steam deck) or from a controller (pressing PS/Xbox button) launches BPM, shows the opening start up video and then "Shutting down Steam..." popup. Yet nothing ever happens. "Cancel" button does nothing. Have to force close steam, and then killall steam command. killall steam does not always work.

Steps for reproducing this issue:

1. Turn controller on, press PS (playstation button) - OR - attempt to stream game from Steam Deck
   -- Edit: launching BPM from the BPM icon results in same behavior.
2. BPM launches
3. "Shutting down Steam..." popup.
