Hello, I am trying to get PySide6 setup using Autodesk Maya's Python executable. I am migrating from Maya 2023 and PySide2 with Wing 8, where I was able to launch Qt GUIs directly from Wing without any issues.

however after upgrading to Wing 11, Maya 2026, and PySide6, I get an error when trying to launch a Qt GUI from Wing.

"This application failed to start because no qt platform plugin could be initialized."

From searching around internet, I see this is a common problem that affects multiple versions of Qt, and it seems that the solution generally revolves around updating environment variables.

Does anyone have any suggestions on how to resolve this? Thanks.
