when run lotus sync wait
ERROR: could not get API info for FullNode: could not get api endpoint: API not running (no endpoint)

As the error indicates, lotus is attempting to share its API over a port which is already being used. Check the API.ListenAddress setting in /Lotus/config.toml and determine what is using that port. Change the ListenAddress to an unused port.
