What I think is happening here is that you have mixed Plasma 6.3 and 6.5 and thus get weird behaviour. We've just upgraded Plasma to 6.5.0 in unstable, but only a couple of packages have migrated to testing yet, the rest will follow in a couple of days. Downgrading libplasma & plasma-activities should fix your issue. When the remaining Plasma 6.5.0 packages have migrated, then you can upgrade everything. Unfortunately, we cannot control directly when packages migrate to testing. When you're using Plasma on testing, look out for discussions on the mailing-list. -- Med vänliga hälsningar Patrick Franz
