Hey there! No need to stress about reinstalling extensions—VS Code has built-in Git support that handles the branch display in the status bar. Here's how to get it back step by step:

• Check if Git is enabled in VS Code
  Open the Settings panel (press Ctrl+, on Windows/Linux or Cmd+, on Mac), search for git.enabled, and make sure the checkbox is ticked. If it was disabled, flipping this on will reactivate VS Code's core Git integration.

• Verify status bar visibility settings
  Still in Settings, search for git.statusBarVisibility. You’ll see three options:

  • Set it to visible to always show the Git branch (even if you’re not in a Git repo, though it’ll be empty then)
  • auto (the default) will show it only when you’re working inside a Git repository
    Avoid hidden—that’s almost certainly why the branch disappeared!

• Force VS Code to detect your Git repository
  If you’re in a Git repo but the branch still isn’t showing, open the Command Palette (Ctrl+Shift+P / Cmd+Shift+P) and run:

  Git: Fetch
  

  This refreshes VS Code’s connection to the repo and should trigger the branch display. If your folder isn’t a Git repo yet, run Git: Initialize Repository first to set it up.

• Reset settings as a last resort
  If nothing else works, it might be a misconfigured setting you missed. Open the Command Palette and run:

  Preferences: Reset Settings
  

  Choose to reset to default settings (you can export your current settings first if you want to keep customizations). This will revert all settings back to their original state, including the Git status bar display.
