Links in Konversation always pop up an Application Chooser?

Hi, got an NVME, so disconnected existing disk, installed that, then installed the latest Mabox. That all worked, but now clicking any links in Konversation always pops up a Choose Application window.

Unsure if this is a Konversation issue, a mime-types issue, or what, but it will not “remember” anything. Thanks for looking.

Konversation is KDE thing. Maybe try to set up a custom web browser to handle links?
