On CachyOS (Arch btw), It works fine (Lutris, Winetricks, Protontricks or whatever you want to use), All the extra features work, However, The main feature of browsing the assets does not, All because "Open assets folder" throws a "There is no windows program configured to open this type of file", Which I am guessing because it does not use a common file picker (Which all the extra features use that's why it works and lets me pick assets), Regardless, Love the launcher and I can't wait for a native one <3.
