ModuleNotFoundError: No module named 'regex._regex'

This error occurs when the Python interpreter is unable to find the regex module. The regex module is not a built-in module, so it needs to be installed separately.

To resolve this error, you can try the following steps:

1. Check if the regex module is installed: Run the command `pip list` in the terminal or command prompt to see if the regex module is listed. If it is not listed, install it using the command `pip install regex`.

2. Check your Python environment: Make sure you are running the correct version of Python that has the regex module installed. You can check the Python version by running the command `python --version`.

3. Check your import statement: Make sure you are importing the regex module correctly. The correct import statement is `import regex`, not `import _regex`.

If none of these steps work, you may need to reinstall Python or the regex module.
