standalone.initialize() QT error

jEchoes — Fri, 14 Jul 2023 07:29:19 GMT

I'm trying to run some processes without opening maya. I'm getting kicked out of mayapy when I initialize maya.standalone. It prints out some errors/warnings about Qt and then leaves mayapy. Im not sure if something else is erroring and the QT messages are just warnings. Any help would be appreciated. Everything I have read doesn't encounter this problem.

In command prompt or PowerShell I ran the following

mayapy

That opens the mayapy prompt. Then I ran these lines:

import maya.standalone as standalone

standalone.initialize(name='python')

Error message:

Qt WebEngine seems to be initialized from a plugin. Please set Qt::AA_ShareOpenGLContexts using QCoreApplication::setAttribute before constructing QGuiApplication. qt.svg: Cannot open file ':/expression.svg', because: No such file or directory qt.svg: Cannot open file ':/expression.svg', because: No such file or directory QWidget: Cannot create a QWidget without QApplication

From here I expect it to stay in mayapy so I can run some python.

It sounds like a plugin using autoload requires the QtWebEngine.

If you disable all of them and try again, do you get the same issue?
