Gitlab 18.6.0: fatal: unable to get password from user

I currently test Gitlab 18.6.0 for FreeBSD. While testing pipelines with the new version I see the following output:

Running with gitlab-runner 18.6.0 (18.6.0)

It is a self hosted gitlab with gitlab-runner 18.6.0.

Is this a general problem or a configuration change that is required with gitlab 18.6.0 that I oversaw?

Thanks a lot! Matthias
