Hello again,
The issue may be caused by conflicting PySide2 installations. You may check for an existing PySide2 installation by starting a Python command line and trying to import PySide2. This should fail if there is an existing global installation.
λ python
Python 3.9.6 (tags/v3.9.6:db3ff76, Jun 28 2021, 15:26:21) [MSC v.1929 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import PySide2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'PySide2'
If the command succeeds, you need to uninstall the global installation of PySide2 so that Designer can use its bundled installation without interference.
Best regards.
Hi Luca,
Thank you! While I didn't have PySide2 installed, it did occur to me to look in Designer's console panel. Turns out I had some old packages in the Python 3.7 site-packages folder (using 3.9.7 now), and it was trying to load shiboken2 from there. Removing that fixed my problem.
Thank you very much for looking into this! I'm thrilled to have a fully functional Substance 3D Designer now 😊
