visual studio crashes when opening QML files

I'm experiencing Visual Studio crashes when opening QML files after installing the extension. The same QML files display fine under Visual Studio 2015 with QT VS Tools 2.3.2.

Environment:

Qt Visual Studio Tools 2.3.3

Visual Studio Professional 2019 Version 16.0.3

Windows 10 Pro (64-bit) Build 1803
