Pyproj conflict with another package google.protobuf.text_format

Code Sample, a copy-pastable example if possible

A "Minimal, Complete and Verifiable Example" will make it much easier for maintainers to help you:

from google.protobuf import text_format
import pyproj

Problem description

These two lines above alone would give me "Segmentation fault (core dumped)" when I tried to run it (build is fine tho).
If we switch the two lines then it can work.

[this should explain why the current behavior is a problem and why the expected output is a better solution.]

Expected Output

Run without error.

You are using an old python and pyproj version. Are you able to upgrade to the latest stable versions and verify the issue still exists?

hi, thanks for getting back, I tried to change the version to pyproj==3.7.1 and python==3.10 but the issue is still there

I am unable to reproduce. Tried on macOS with Python 3.10-13, using venv and pip install protobuf pyproj, then

python
from google.protobuf import text_format
import pyproj

Tried on Ubuntu 22/Python 3.10/Pyproj 3.6.1 (using system packages);
Windows x64, Python 3.10, (venv, pip install protobuf pyproj): all with no error
