I have already disabled SIP on my macOS.

sudo py-spy record -- python3
Python 3.10.5 (v3.10.5:f377153967, Jun  6 2022, 12:36:10) [Clang 13.0.0 (clang-1300.0.29.30)] on darwin

>>> Error: Failed to find python version from target process

There are last few lines of the debugging output, which the command runs with RUST_LOG=debug:

After looking into the source code, it seems like function get_python_version hasn't cover the path like this in macOS.
