Purge Git database entirely
Erase all history in the Git repo to start over with all the current files. This also clears big file records in the Git database.
git checkout --orphan newBranch # Create an orphan branch to hold the files
git add -A && git commit # Add all files and commit them
git branch -D main # Deletes the main branch
git branch -m main # Rename the current orphan branch to main
git push -f origin main # Force push main branch to remote (e.g. github)
git gc --aggressive --prune=all # Remove the old files in the database
