Application: plasma-discover (6.4.4)

ApplicationNotResponding [ANR]: false
Qt Version: 6.9.1
Frameworks Version: 6.17.0

-- Information about the crash:
While attempting to install a Flatpak package (specifically sh.ppy.osu) Discover crashed while still displaying progress bar on the package's view.
The app was opened using a link from Flathub.
Manually checking using flatpak CLI, the installation finished without issues.

The reporter is unsure if this crash is reproducible.
