How to fix the error: bad signature 0x00000000 index file corrupt

I have not been able to update my repository because I'm getting this error below when I commit the project.

I have been told to remove the index file and run these commands del .git\indexand git reset however there no index file in my project file (see below my project file)

Any idea how can I fix this error?

my project folder I cannot see the index.file

If you're using git worktrees, the steps wont work, as the file isn't located at .git/index. It's located in the parent repo, at ./git/worktrees/[child name]/index. Delete that file.
