usdView error: QWidget: Must construct a QApplication before a QWidget

[Lucas3Dspain]

I'm trying to add the plugin to usdView.

I'm getting this error: usdNodeGraph using qt binding: PySide2 QWidget: Must construct a QApplication before a QWidget

When I open usdView the NodeGraph menu appears but when I do Open Node Graph I get the error and usdView closes.

I'm using windows, and running this .bat file.

@ECHO OFF

SET "PYTHON=%USERPROFILE%\AppData\Local\Programs\Python\Python39"

SET "PATH=%USD_INSTALL_ROOT%\bin;%USD_INSTALL_ROOT%\lib"

usdview.cmd "someFilepath/prpSimple.usda"

Okay, I made it work using USD 21.08,.

@1xinghuan are there plans to update this to be compatible with pyside6?

edit: it opens but as soon as I interact with the UI it crashes

Lucas, did you ever get this working fully? I'm trying to use it with the current usdview release from Nvidia (24.08)
