Bug report

In previous versions, a shebang line like #! C:\full\path\to\executable or #! C:\venv\Scripts\python worked to specify the executable used to run the script. With the 3.11 py.exe launcher, this pattern is not recognized and uses a default Python interpreter instead.

I initially reported this in the comments of issue #94399 which was resolved several months ago.
