Job Failure: "could not determine windows version"

The runner reports an system error saying that:

Running with gitlab-runner 12.4.1 (05161b14)
  on Windows 10 Pro 1903 Docker 9rAAKdGg
ERROR: Preparation failed: could not determine windows version
Will be retried in 3s ...
ERROR: Preparation failed: could not determine windows version
Will be retried in 3s ...
ERROR: Preparation failed: could not determine windows version
Will be retried in 3s ...
ERROR: Job failed (system failure): could not determine windows version

What does it mean with “could not determine windows version” and how to solve this?

The same situation, please help

Seems that Windows with the base version 1903 is not supported yet.
