Hmm, I see. Thank you very much for purchasing the program, but I'm very sorry for the inconvenience! I've never heard of this particular issue before...
I'm wondering if this is happening because it can't open a file browser. Internally, I'm using the zenity Golang package to handle opening file browsers, which requires `zenity`, `qarma`, or `matedialog`.
Does MX-Linux come with any of those installed? If not, is it possible to install it and see if that resolves the issue? Also, which desktop or window manager are you using? KDE?
