Crash looks to be entirely in non-KDE code, and also Plasma 5.14.5 is no longer maintained. We're on 5.20 now. Nothing we can do here, I'm afraid, sorry!

Please file a new bug report if it happens again in Plasma 5.18 (the LTS version) or whatever the latest Plasma version happens to be in the future.
