Action fails when running it with Checkout Action@v6

[Sevenlive]

The Github Action consistently fails with a fatal: could not read Username for 'https://github.com/': No such device or address error during a git push operation when utilizing actions/checkout@v6.

The action executes successfully and completes the git push operation without any issues when using the previous version, actions/checkout@v5. The failure appears to be related to how version 6 handles authentication or the Git environment setup within the runner.
