My guess would be that your previous world update was interrupted for some reason and you still have some qt packages that didn't update. You can check if they match by looking at: qlist -Iv dev-qt/
Finish your world upgrade.
please test the suggestion and reopen, if the problem still remains.
That fixed it, thanks!
