STEPS TO REPRODUCE
1. Install arch with kde plasma
2. Add the kde-unstable repo to /etc/pacman.conf
3. Update to Beta 2

KDE Plasma Version: Plasma 6.0 Beta 2 from kde-unstable
Qt Version: 6.7.0beta1-1

ADDITIONAL INFORMATION
Happened on two of my PCs, both running arch. They were set up seperatelly. Issue occured when updating from stable to unstable and then from beta 1 to beta 2. Issue doesn't occur in Beta 1.
