error when installing dbt-core in python virtual environment?

Error message:

ImportError: DLL load failed while importing dbt_extractor: The specified procedure could not be found.

The problem I’m having

The context of why I’m trying to do this

Trying to install dbt core and dbt-sqlserver in python virtual environment so that I can connect and run my python scripts with dbt.

What I’ve already tried

  1. check python version, which is 3.9.0.
  2. Installed required dependencies, python and git. The only thing is that I have installed python 3.13.0 and anaconda a few months before the installation of 3.9.0. But I have uninstalled and deleted everything with python 3.13 and anaconda.
  3. Set up a virtual environment correctly.
  4. Installation of dbt core with the correct command.
  5. Confirmed with the correct Microsoft Visual C++.
  6. when I check the dbt version, it showed: ImportError: DLL load failed while importing dbt_extractor" error when installing dbt-core in a Python virtual environment.

Some example code or error messages

Put code inside backticks
  to preserve indentation
    which is especially important 
      for Python and YAML!

Please post the commands you ran to create your virtual environment and install dbt.

Are you following this guide? https://docs.getdbt.com/docs/core/pip-install

Thanks.
Yes, I followed the guide to install dbt-core.
Here are the commands used:
python -m venv dbt_VENV

Scripts\activate
python -m pip install dbt-core

dbt --version
Then the error message as in below:

You also need to install your adapter. E.g. pip install dbt-postgres
