MoonDeck does not start app in time

[jonnyml]

I've been using Sunshine/Moonlight for a long time with no issues and thought I'd try using MoonDeck to speed the streaming process along.

However, after setting everything up, when I start a game using the MoonDeck button, my Steam Deck connects to my PC but doesn't load the game. It sometimes loads Steam Big Picture mode, but it'll back out, disconnect the stream and show the notification "MoonDeck didn't open the app in time" or something to that effect.

I've checked my Sunshine settings, the command path, and the MoonDeck/MoonDeckBuddy settings and nothing solves this. Does anyone have any suggestions?
