I've downloaded and extract 0.6 twice now, and the launcher still won't start. I'm on Kubuntu 20.04 and lots of other games that use the "same" Ren'Py launcher work fine. 0.5 worked fine. I've got 32 GB RAM, 10+ GB of free space on the volume the launcher lives on, and a 4+ GHz 8-core processor, so I don't think there's a resource problem. Suggestions?
