mayapy (Autodesk's Maya python interpreter) is not recognised

[daniele-niero]

Type: Bug

Behavior

It appears that with the latest version of Python Extension (2026.4.0), issue #20793 has returned.
When selecting Autodesk's Maya embedded Python interpreter (mayapy), Python Extension reports the interpreter as invalid.
This worked with previous versions and, as far as I can tell, the last working version was 2026.2.0.

Steps to reproduce:

1. Using Autodesk Maya 2024
2. Install Python extension v2026.4.0
3. Select C:\Program Files\Autodesk\Maya2024\bin\mayapy.exe as Python interpreter
4. The following notification appears: "An Invalid Python interpreter is selected, please try changing it to enable features such as IntelliSense, linting, and debugging."
