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.
Most of the package should now be fixed

Fix confirmed here, too!
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.

This seemed to be sorted, yes.
