Damn, maybe it's an issue with umu-launcher? or proton, idk, I'm not giving up tho.
Also I tried to do a full run and honestly I don't even know if it finished correctly, I went to sleep and left it open more than 40 minutes but it stayed there, after I closed it, the window name changed to "Waiting for generator to terminate..." but I waited a lot and it never did, I think the program just crashed, it didn't give me too many logs but I'm uploading them anyways: https://filebin.net/kq4yqwqoj2fce16c
