Git and Commit tool windows are completely empty

Problem

Git and Commit tool windows are empty, there are no branches, changed files, repository history log, commits etc. Options to enable Git integration are unavailable, file changes are not recognized, and no errors are displayed in console logs.

Cause

This behavior occurs due to Version Control System (VCS) directory mappings being improperly configured in the project settings, resulting in a lack of association with Git.

Resolution

To resolve this issue:

1. Navigate to the project settings:
   • Open IntelliJ IDEA, go to File > Settings (or press Ctrl + Alt + S / ⌘ + , on macOS).
2. Check the directory mappings for the VCS:
   • In the settings window, navigate to Version Control > Directory Mappings.
   • Ensure that your project's root directory is listed and associated with Git.
3. If no mappings are found, manually add them:
   • Use the + button to add your project's root directory and select Git as the associated version control.
4. Apply changes and confirm that Git integration within the IDE is restored.
