Sorry it looks like the Qt 5 update started but didn't complete, finishing it now..

For what is worth, all the appimages that I have also give this error, just to name one: audacity v 3.5.1.
Comment 7 Jonathan Riddell 2024-07-23 21:14:10 UTC 
Most of the package should now be fixed

I can confirm after updating, VLC, KDevelop, Corectrl and QOwnNotes all launch successfully.
Comment 9 JPS 2024-07-23 21:35:30 UTC 
Fix confirmed here, too!
Comment 10 JMB9 2024-07-24 00:01:52 UTC 
I can confirm the fix, too!
  (Wanted to make a bug report, found this one, updated my system ... and now the problem is gone.)
Thanks for the fast fix ... I hope the various session save problems may also get fixed soon (Bug 488744),
which is present since 6.0 to 6.1.3 - but did not show with 6.1.0 ... and being a moving target.
