I recently upgraded to Kubuntu 21.04. Soon, i realised that after taking screenshots (using Spectacle) and saving them, i recieve this notification where kdeinit5 crashes.
The crash, occurs only when the notification tries to generate a thumbnail of the screenshot. So i guess it has something to do with thumbnail generation that is crashing kdeinit5.
This is the only time when such a crash occurs. I am not facing any crash elsewhere.
Here is the crash report.
Application: kdeinit5 (kdeinit5), signal: Segmentation fault

I have the same problem, but it seems it was resolved on the latest KDE 5.81. Unfortunately, unless you add the backports repositoriy, you should wait for the 21.10 release.
1Try the following and see if it works:
kdeinit5 --replace
