The default button in the popup is "Ignore". It is safe to ignore this error. We just show more occurred errors since 4.0.
As an UX improvement, the auto-complete function could retry this operation on this error.

".git/index: index file open failed: Permission denied" is generally an indication of another active git process in the repo (e.g., VS Code runs its own git process).

stop / kill a concurrent (hanging?) git operation
Or did you run git with a different account or admin privileges?

[NissimBendanan]

Yes, maybe my bad: I run visual studio as admin to debug a service that I run. So, it can be that some of the git files got the admin owner ….
