Cannot reproduce.
Comment 2 Nate Graham 2021-03-09 02:21:17 UTC 
The crash does not appear to be in any KDE code. Does this still happen to you in either Plasma 5.18 (the current LTS version) or Plasma 5.21 (the latest released version)? Preferably when using the latest Qt version (5.15.2 or newer)?
