If you run 'sudo apt install dbus-x11' your GUI apps should work. Somehow the WSL system is not flagging dbus-x11 as a required dependency of x11/GUI apps.

Thank you @TheNavyBear for your help. Even in Feb 2025, this problem persists. Your solution worked for me regarding another GUI app that was giving the same error message =)

honestly, I'm not expect this problem will get fixed, because this is a small problem that just have some warning to english native people, but if you're some non-english user, it's a little bit annoy. but still thank you to reply this dusted problem.

It's not just a warning though. The app that I was having a problem with would not save any of its settings at all, so I was stuck with the defaults, until after I installed the dbus-x11 package.
