Comment

I found that the crash is actually caused by the remote HEAD pointing to origin/master, which no longer exists, causing the Tip is null.

I not sure how the remote HEAD ended up in this state since I cloned the Windows-universal-samples repository a long time ago. It might be an edge case.

Here are the steps and git commands I tested that can lead to the HEAD pointing to a non-existent branch:

1. Create a new repository
2. Clone the repository
3. Make changes and commit them
4. git push -u origin master
5. git checkout -b main
6. git push -u origin main
7. Update the default branch to main on GitHub.
8. git remote set-head origin master
9. git push origin -d master
10. git branch --delete master
