Icons-Only Task Manager Settings empty

What I am trying to do:

Access the taskbar settings to change single-click-on-icon behavior

The issue:

The Icons-Only Task Manager Settings are completely empty and I cannot access anything. Clicking the icons in the left sidebar has no effect.

Steps to reproduce:

Right click on the taskbar

Left click “Configure Icons-Only Task Manager..”

Screenshot:

hi, welcome.

you should go to your system info page and paste the contents here.

this is definitely not normal and i assume you have tried rebooting your machine.

This generally means the page is broken, likely by a missing QML module or a code error introduced by the distro or a 3rd-party widget that’s overriding things.

To find out what exactly the problem is, first run this in a terminal window:

journalctl --follow --user-unit plasma-plasmashell.service

Then open the config dialog again.

Some errors will be printed to the log. Copy and paste them here.
