I'm new to Heroic Game Launcher. I'm using the Heroic game launcher flatpack. I installed the game Flashback via GOG in Heroic under Kubuntu 24.04.
I'm using Wine version "Proton - GE-Proton-latest".
In Heroic, if I click Play the game, the game starts and then crashes in 5 seconds. If I change to a different proton version the same thing happens.
I have tried changing different UI settings without any impact.
If I go to Flashback (settings) in the Heroic UI and scroll down to "run EXE on prefix" (next to "winetricks"), then click on the flashback.exe , the game starts and works every time. I have reproduced this a few times. Why is "run exe on prefix" different than how Heroic normally starts the game via "play"?
