hey guys! thanks for the quick answers. i tried some stuff.first of all, I am running the custom wine package provided in this thread, with the exact install method, on ubuntu 20.04. I use firefox as default browser and, even though i have some crazy addons, it usually does its job or notifies me if something went wrong. The issue is, as mentioned above, when i press on "proceed to paysafe" firefox does not open at all. if its already open, it does not create a new tab or anything... using xdg-open in terminal works just fine.I made myself a shortcut so i dont have to run the play.sh from terminal all the time, but right now i tried it because usually the terminal logs the complains. when i start the game it tells me it cant find some library (libncurses.so.5) but that has been the case ever since i installed the game, and it works just fine so thats not the issue. BUT when i try to "proceed to paysafe" or any other link of the gemstore (for example the privacy policy terms of sale you name it) it gives me an error message"XPCOMGlueLoad error for file /usr/lib/firefox/libmozgtk.so:libpng16.so.16: failed to map segment from shared objectCouldn't load XPCOM."which sounds like he knows firefox is my standard browser and wants to open it, but somehow cant.any thoughts? first thing that comes to my mind, that could cause the issue here, is the standard apparmor profile for firefox (which i am using). tomorrow i will try again with apparmor turned off. thanks again for the help
