Aaah - so this is the reason why Elisa, which I installed through flatpak is like : «I dont know how to play this file, I can only play audio files» when i try to drag&drop wavs/oggs to it. Yes, hundred percent agree - this is unacceptable behaviour when it comes to ux. I hope it will be fixed.

For what it’s worth, my KDE file browser would freeze up when I had a WebDav network drive to a server that went offline, not exactly elegant either, just opening my home folder and randomly after a second or two …… all software can bug in bad ways.
