I run Kubuntu 22.04 LTS and have a strange issue. Dolphin is working fine as my file manager and set as default, but when I try to launch it via another application (e.g. "browse local files" in steam or "view destination folder" in qBittorrent) it won't launch.

It seems there's some problem with the system for launching the OS default file manager. When I attempt this, a blank icon appears in the taskbar (labelled WSLView) with a spinning circle, then disappears after a second or two.

Any ideas?

EDIT: I found the location of the application which was erroneously being launched and deleted it. i.e. I deleted wslview.desktop from usr/share/applications. that seems to have solved my problem.
