[UMU Error] Runtime Platform missing on ALL Heroic versions (Flatpak/AppImage/Native)
🐧linux
Hi everyone,
I have a critical issue with the UMU runtime on Manjaro (Kernel 6.18). The game fails to launch because the runtime is missing, and Heroic refuses to re-download it.
The Error:
What I have tried so far:
1. Tested on ALL Heroic versions: Official Repo, Flatpak, and AppImage.
- Result: Exact same error on all of them.
2. Manually deleted the UMU folder (
- Result: Heroic does not start a download. It just fails immediately when I launch the game.
3. I am using Proton-GE (not Wine). The game only runs if I disable "Use UMU", but I need this feature on.
System Info: Manjaro Linux, Kernel 6.18.3.
It seems like Heroic is unable to fetch the runtime files from the server or is blocked from creating them. Has anyone seen a case where the runtime simply won't download?
Any help is appreciated.
