I am unable to connect to a Python 3.12 process on Windows from py-spy (also running under Python 3.12). It fails with the following error message:

py-spy top --pid 37396
Error: Invalid access to memory location. (os error 998)
Reason: Invalid access to memory location. (os error 998)

Attaching to a running process of Python 3.11 or below works (even if py-spy is running from Python 3.12).

Versions

Python: 3.12.4
py-spy: 0.4.0
OS: Windows 10 Enterprise (Build 19045.5011)
