-- Information about the crash:
i have kde neon installed and i have been facing this bug for  very long time.

i get the notice that an update is available.
i click on the icon and discover gets opened on updates checking page. i am forced to keep the page open because if i keep some other window in foreground, discover crashes. 

this is repeatable 100% of the time for me.

The crash can be reproduced every time.

How strange. Do you by any chance have any KWin scripts, Window Rules, or custom shortcuts that trigger on windows being made inactive?

I had this crash, and it was after I switched to another window, so maybe it is the same situation.
I hope the crash information helps.
Thanks!

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with either Plasma 5.27.12 (the current LTS version) or Plasma 6.3.2 (the latest released version)?

If you can still reproduce the bug, please change the Status to "CONFIRMED". Thanks.

I have just tried Discover in distinct situations, and it did not crash, so the bug seems gone for me.
Versions here are Plasma 5.27.11 and Discover 5.27.12.
