I have Monogame setup under Ubuntu 21.04 (Xorg) and everything is working fine besides mgcb-editor. I have it installed through the command line with the command
dotnet tool install --global dotnet-mgcb-editor and it installs successfully and I registered it right after as well. Unfortunately whenever I try to launch it it just immediately crashes and gives me this error message:
System.NullReferenceException: Object reference not set to an instance of an object. at Gtk.Widget.DrawnSignalCallback(IntPtr inst, IntPtr arg0, IntPtr gch)
I’ve looked around and saw that not having gtk-sharp3 installed would cause an issue like this so I installed that as well and I’m still getting the same error. I’ve reinstalled multiple times with still no luck. Any help would be appreciated.
