Source Control panel shows "no Git repository" despite git extension successfully detecting repo

[colin-luke]

The Source Control panel displays "The folder currently open doesn't have a Git repository" and offers to initialize one, even though the Git Output log confirms the repository was successfully opened.

Git Output log shows:

[Model][openRepository] Opened repository (path): d:\Development\AWS.Integration
[Model][doInitialScan] Initial repository scan completed - repositories (1)
All git commands (status, fetch, diff, for-each-ref) execute successfully
Troubleshooting steps attempted:

Confirmed .git directory exists and is valid
Set git.path to C:\Program Files\Git\cmd\git.exe
Enabled git.autoRepositoryDetection
Removed hidden attribute from .git directory
Removed core.worktree from git config
Removed git.scanRepositories (warned about absolute paths not supported)
Multiple window reloads
Environment:

OS: Windows
Git: 2.53.0.windows.3
Repo hosted on Azure DevOps
Azure Repos extension installed
Repo has many branch entries in .git/config (~60+)
The git extension backend works correctly (all commands succeed from terminal). Only the Source Control panel UI fails to render the repository view.
