Activity manager

My laptop freezes whenever I try and go into settings for this. I can switch between screens but can’t change their names etc. Also the widget Activity Bar works but the other one - Activities (shows manager) produces the freeze if selected. Anyone help?

Is kactivities5-imports installed?

yep. running v5.16.0-3.1. Could it be a conflict with my desktop theme (Ghost)?

No idea, but it might be possible.
Does switching back to “Breeze” help?

Another thing I would try is disabling Compositing (Alt+Shift+F12 or in “Configure Desktop”->Display and Monitor->Compositor). Although I don’t really think it’s a problem in this regard if only the activity manager is affected…
