[QGIS-Developer] QGIS Unexpectedly Crashing

[Catania, Luke A ERDC-RDE-GRL-VA CIV]

Oddly while pyqtgraph is pip installed and used in other parts of the pluign, it is not used in any part of this UI, so wondering how it is being referenced.

Once it happens sometimes it continues to happen, and I have to delete the QGIS directory in AppData\Roaming\ which is annoying because I have my plugin there and I need to copy it to another directory and then copy it back after running QGIS for first time to have the directory recreated.

My guess: You've installed pyqtgraph via pip or some binary wheel, and it's using a different Qt library vs what QGIS is bundled with.
