Description Bacteria 2025-05-24 06:34:27 UTC 
Cannot switch to other activites only the current one to be in focus

SUMMARY
I have 2 activities. On login I am on the "Default" one. No way to switch to the 2nd one. I have tried using activity pager, activity switcher, walk through activities shortcut. I feel like the switching logic is broken. 

I have deleted all activities and created them again but still unable to fix this. When I delete the current activity, it switches me to the next active one but still can't switch.

I even tried assigning a dedicated shortcut to switch to an activity and even that doesn't work.

STEPS TO REPRODUCE
1. Have a at least 2 running activities
2. Try to switch activity using any of various UI or keyboard shortcuts

OBSERVED RESULT
Nothing happens, kwin stays on the current activity

EXPECTED RESULT
Kwin should switch to the other activity

Comment 1 Nate Graham 2025-05-27 17:33:02 UTC 
I can confirm all activity-switching keyboard shortcuts appear to be broken now.

I can however switch using the Activity Pager, so switching in general isn't broken; just the shortcuts.
