Unable to run a Pyside6 application in QtCreator

JM baubet

I'm on MAC OS 13.1 (Ventura)
I have a Python QML application in QT 6.4.1 QT Creator 9.0.1, python 3.9

When I want to run my application I get the following message during compilation.

Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/PySide6/scripts/project.py", line 227, in <module>

I have the same message when I run QML preview.

When I launch the designer Qt Creator crash... or I have the message :
Cannot open this QML document because of an error in the QML file:
Line: 0: The Design Mode requires a valid Qt kit

My code is running by the command 'python3 main.py'

I suspect a problem in my QTCreator environment, but I can't find anything wrong.
I already reinstalled all Qt without any change, I also tried with QTCreator 9.0.0

I am desperate

How did you create your files? It seems there is an invalid character (0xb0 / Vertical tab) in your project file which causes the JSON loader to throw. The project file should be UTF-8, or better, plain ASCII , as should the source file names. Similar for the .qml files.

I create my files with QtCreator.

Have you looked at them with Qt Creator's binary editor (Open File With)? - You somehow have invalid characters in there.

JM baubet

@friedemannkleint I never edited the files with any other editor

I looked at the files with a Hexa editor and I can't find the character 0xb0

I have partially solved my problem.
When I create projects on my removable disk, nothing works. If I create the project on the main disk everything works normally.

I have to find out why...

I know this post is old, but in my case when I got this error, I was missing the tomlkit module in my python installation.
