I'm able to reproduce this bug on the Fedora 33 after enabling this option in the flameshot settings: `Save image after copy`.
Looks like kdeinit5 crashing when trying to make preview of taken screenshot.
Here is stacktrace of the crash.

kdeinit crashes on this line: https://invent.kde.org/network/kio-extras/-/blob/v20.12.3/thumbnail/thumbnail.cpp#L315
Comment 6 Ilya Bizyaev 2021-03-18 11:49:54 UTC 
Can reproduce. To get Flameshot to show a preview, I have to choose saving to a file, not copying.
Comment 7 Ilya Bizyaev 2021-03-18 11:50:51 UTC 
Multiple users reported on https://www.reddit.com/r/kde/comments/m5nq4r/kdeinit5_segmentation_fault_when_creating_image/, confirming.
Comment 8 Yaroslav Sidlovsky 2021-03-18 12:35:58 UTC 
Probably bug was introduced in this commit: https://invent.kde.org/frameworks/kio/-/commit/ee3d4e0e275bc8cf62757fd4b5e9ed400525dd8e.
On my machine crash is gone after reverting it & rebuilding libKF5KIOWidgets.so.
