ERROR: Job failed (system failure): prepare environment: exit status 1. Check https://docs.gitlab.com/runner/shells/index.html#shell-profile-loading for more information

Also I get this error when run gitlab-runner --debug run

error=stat /home/hpuser/.gitlab-runner/config.toml: not a directory

I checked the mentioned path and saw in user's home directory only there is a .gitlab-runner file instead directory and contains the config information and checked the /etc/gitlab-runner/ as root user and saw there is config.toml with content same as home/hpuser/.gitlab-runner/ file
