I plugged in another monitor to my laptop and using KDE under Fedora 36 (all updates applied).
I wanted to add new widgets to the extended screen (it was just showing a background image), I right clicked and added a new panel -- I think it added it, there is a black bar accross the top of the second screen now. However, doing anything with it, such as right click-add widgets crashes the panels, everything disappears except the laptop screen's desktop icons and re-appears after 30 seconds.

My aim was to add another panel and some items so it would be easier to use the second screen..
Any ideas what to do?
Thanks!
