I had a similar issue in Replit where my local got out of sync with Git. I opted to go with the local discard any differences. Steps below. All executed in the Shell.

~/workspace$ rm -f .git/index.lock

~/workspace$ git rebase --abort

~/workspace$ git fetch origin

~/workspace$ git branch backup-main origin/main

~/workspace$ git checkout main

~/workspace$ git add -A

~/workspace$ git commit -m "Replace codebase with latest local version"

~/workspace$ git push --force-with-lease origin main
