.git folder may cause problems in your git repository. If you want to delete all your commit history but keep the code in its current state, it is very safe to do it as in the following:
git checkout --orphan latest_branch
- Add all the files
git add -A
- Commit the changes
git commit -am "commit message"
- Delete the branch
git branch -D main
- Rename the current branch to main
git branch -m main
- Finally, force update your repository
git push -f origin main
