Heroic will prefer System umu if it finds it. Check your game log for the wrapper path

This output is really strange. Are you running a development environment of Heroic?

What's going on here? Anyways, there are quite a few things happening here I'm not sure about. Perhaps you're better off using Flatpak Heroic, that'll mask away most distro weirdness @潘达 (Panda)
