There is an error message on startup if you are using latest Vuplex

Assets\Vuplex\Ready Player Me\VuplexKeyboard.cs(9,17): error CS0619: 'HardwareKeyboardListener' is obsolete:
'HardwareKeyboardListener was removed in v4.3 because WebViewPrefab and CanvasWebViewPrefab now automatically handle keyboard input by default. 
Please remove your code that references HardwareKeyboardListener, and keyboard support will still work. 
For more info, including details about how you can still access keyboard input programmatically, please see this article: https://support.vuplex.com/articles/keyboard'
