This is totally useless for the game and potentially harmful if the user has other windows applications installed in the default wineprefix (which is ~/.wine). I had no problems because I don't use much wineprefix Then restart the machine and try to open the figther z again with proton 5.21-ge Open winetricks and click on '' select the default wineprefix '' and then click on '' Delete ALL DATA AND APPLICATIONS INSIDE THIS WINEPREFIX ''
Try it here, i'm a beginner but maybe it works
