How to find out the config and modify --working-directory after incorrect "gitlab-runner install"?

Hi guys, I'm facing with a quite tough problem. For my project, there has been execute several times gitlab-runner install to install a service without --working-directory to figure out the builds directory, and each time execute install command in different directory. So I create the new runner and install a new service with --working-directory option to remove the incorrect working directories created before. However, it wouldn't be removed, and the gitlab-runner will execute the builds job at the incorrect directories. And what's the worse is, I remove the directory manually. So, it will report the Error bellow.

Running with gitlab-runner 12.6.0 (ac8e767a)
  on dst08553.xxxxx.ios qV2bEYxH

How can I solve the problem?
