Comment 6 Aleix Pol 2021-09-28 17:37:18 UTC 
Could you maybe reopen a new one? This is a very weird freeze too where Qt seems locked with itself (???)
Comment 7 Aleix Pol 2021-09-28 17:37:29 UTC 
PS: I cannot reproduce

New crash information added by DrKonqi

plasma-discover (5.24.3) using Qt 5.15.2

- What I was doing when the application crashed:
Click install and open the .ref on https://flathub.org/apps/details/us.zoom.Zoom

flatpak: Ensure we fall back to appending .desktop

AppStream still cannot do it itself for some reason, found this trying
to open Zoom's flatpakref.
