Crash after change to next song on playlist while minimized

[aqzxt]

I'm running on Fedora 31 KDE.
I cannot run it on terminal; no parameters no help, it just opens it the program. So no way to log errors.
It started crashing after I made some changes to the layout.
After crashing I see that it opens a new dialogue pop-up for a second and closes itself.
I managed to capture a screenshot.

It happens only when minimized.
It does NOT happen, however, when the window is inactive; in a restored or maximized state.

Please can you try to do a backtrace ? see this https://www.guayadeque.org/viewtopic.php?f=3&t=468

I tried again running in the terminal with guayadeque --help. It worked. But don't know if it's enough.
