I've been using Heroic to play a couple of games on my Steam Deck and haven't had any trouble until trying to launch Victor Vran. I click on the "Play Now" button, I see the "Launching" and "Playing Now (Stop)" button in the Launcher... and then nothing happens. The game never launches, a window never opens, and the button in the launcher reverts to "Play Now." Heroic doesn't crash and I'm able to access logs for both the game and the Heroic software itself, no problems.
My log is attached here. I'm seeing a funny segmentation error that I'm not familiar with, but I don't know if that's the source of the problem or if something else is going on. Hoping someone can help. Thanks!
