Error: Failed to find a python interpreter in the .data section

[olumide-x]

I am running py-spy (version. 0.3.14) on the following simple example (from the GTK python docs) as follows

py-spy record -- python test.py

on Windows. The application ran for a short while but then crashes with the error

`Error: Failed to find a python interpreter in the .data section`

Same for me on Windows 11 and Python 3.11.9

[jairov4]

may be is any page indicating which version of python works?

[jairov4]

I found it works on Python 3.9 on windows but unfortunately it is useless for my case, my project use python 3.11 syntax :(

[benfred]

This should be fixed by https://github.com/benfred/py-spy/pull/718 -

[benfred]

I think this should be fixed in the 0.4 release. Can you try it out and let me know?

If this is still not working please re-open the issue
