Code change:
So, whenever I open Player, it starts installing Roblox, finishes, and does nothing. Even when launched from the website, starts installing, finishes, and most likely just exits. Logs show nothing important. However, when trying open Studio, the error saying " not found". Steps to reproduce the behavior: the grapejuice package (just write grapejuice in the with pkgs section) wine-wayland package (not sure if it is required, however I did) Grapejuice (I used rofi (drun), but I suppose $ would work) the message box that pops out (from wine), press "Install" to install the wine-mono thingy press the Open RobloxPlayer button, or go into Player, Initialize and Install Roblox, the behavior is the same Roblox installing and doing nothing... I expected RobloxPlayer to actually open, not install and exit... <!-- --
