Probably in some way related to:

No search results in application launcher

I installed Manjaro about a month ago and it worked fine, until a few days ago I did an update with pacman -Syu. Since then, whenever I type anything into the Application Launcher’s search bar, no results are shown. I’ve tried rebooting, but that has not had any effect. I would appreciate any help with this issue. Thank you.

No search results in application launcher

What the people upstream did is to remake the entire code for the application launcher (commited ~6 months ago) and they probably did some mistakes regarding the krunner (search) instance. (It seems that they only create one instance of the search - and the code is trying to bind several kickoff applets to the same search instance, which results in this buggy behavior)
