Cant run GOG games through STEAMOS

[Sickteddy]

Hello,

I need help with an issue related to games installed through the Heroic Launcher. (STEAM DECK)

I installed several games in Desktop Mode using Heroic and created their shortcuts for Steam. However, when I switch to Game Mode / SteamOS and try to launch any of those games, they never start. The screen always returns to the game’s page without showing any visible error.

I’ve already tested different Proton versions (including Proton Experimental and GE-Proton), but the behavior remains the same. Interestingly, if I launch the same games directly from Heroic in Desktop Mode, they run without any problems.

Thanks.
