Follow-up Comment #25, bug #61017 (project octave):

I'm not sure whether I read the backtraces correctly (I only have a very
limited understanding of Qt). But it looks like you are experiencing a
dead-lock while initializing the QApplication object. Thread 1 (the GUI thread
afaict) seems to be waiting for some other thread. But I'm not sure for which
thread it is waiting. All other threads seem to be in a waiting state, too.
Maybe some Qt expert can make more out of this.

Maybe this is something that has been fixed in the meantime (although Qt5.15
no longer receives any open updates from upstream unfortunately).
Could you check if you see the same error with one of the nightly builds from
octave.space? You can download those from here:
https://buildbot.octave.space/#/download

It would probably be most interesting to see if the octave-mxe-default-w64
build is working for you (once it has finished compiling).
