Hey! It looks like your issue might be due to Flatpak's sandboxing. Since your Steam is installed via Flatpak, it might not be able to see the Stardew Valley AppImage. You can try using **Flatseal** to give Steam broader permissions, allowing it to access your Stardew installation. Alternatively, for better compatibility, consider installing Stardew Valley directly through Steam instead of using the AppImage. That should make things work smoothly on your Fedora setup. Let me know if this helps!
