Discover 5.24.4 (Kubuntu) hangs on "about" screen - totally unresponsive

1. System info:

Operating System: Kubuntu 22.04
KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.92.0
Qt Version: 5.15.3
Kernel Version: 5.15.0-41-generic (64-bit)
Graphics Platform: X11
Processors: 20 × 12th Gen Intel® Core™ i7-12700K
Memory: 31.1 GiB of RAM
Graphics Processor: Mesa Intel® Graphics

2) Discover version 5.24.4

3) Expected: clicking on "About" in Discover doesn't make the program unresponsive.

4) What happened instead:

Immediately after logging in to my Kubuntu user session, opening Discover and clicking the "about" tab in the lower left corner displays the "About Discover" information correctly. Then the app becomes completely unresponsive. After the app becomes unresponsive:

* I can move the window, maximize, and minimize it. After doing so, the application window is painted with my desktop background instead of the expected application information.

* Selecting "close" shows me a notification that the app is not responding, and allows me to terminate.

(edit) After submitting this report, Firefox became unstable and crashed twice.
