================================

The issue is caused by a conflict between the cached Python environment and the attempt to downgrade pip to version 24.2, while the setup-python action installs the latest version by default (currently 25.1). This discrepancy can cause compatibility issues if the cached environment includes dependencies or configurations tied to a different version of pip.
Here are a few recommended solutions:

1. Use the Latest pip Version:
   If your project doesn’t require a specific version of pip, consider using the latest version (currently 25.1) to avoid potential conflicts with cached dependencies. This approach eliminates the need for managing multiple versions and ensures compatibility with the latest packages.


2. Explicit pip Version Management:
   To avoid version conflicts, install the required pip version (24.2) right after setup-python action. This ensures the environment aligns with workflow expectations:

steps:
  ...

  - name: Set up Python
    uses: actions/setup-python@v5
    with:
      python-version: '3.9'

  - name: Install specific pip version
    run: python -m pip install --upgrade pip==24.2

  - name: Restore cache
    uses: actions/cache@v4
    with:
      path: ${{ env.pythonLocation }}
      key: ${{ runner.OS }}-${{ env.pythonLocation }}-${{ hashFiles('requirements/REQUIREMENTS-CI.txt') }}
