Launching the plugin crashes QGIS

[steez-k]

I recently downloaded the plugin and PyQtWebEngine via OSGeo4W Shell (C:\Program Files\QGIS 3.40.2\ etc). Shortly after clicking the plugin, QGIS crashes and closes before the menu can even load. The "Qgis2threejs Exporter (WebEngine)" option is available rather than the WebKit so I'm unsure as to why the plugin crashes. Any help would be appreciated!
