"There has been a runner system failure, please try again" - GitLab Demo Cloud

I redeemed the invitation code for the GitLab Demo Cloud yesterday , I was looking to complete the hands on activities of the GitLab Certified Associate Self-Study + Exams course, but I’ve been getting these error mesages when my CI pipelines run:
“Running with gitlab-runner 14.0.1 (c1edb478)
on spt-gitlab-runner-manager QWk2Hp5E
Resolving secrets
Preparing the “docker+machine” executor
ERROR: Preparation failed: exit status 1

ERROR: Preparation failed: exit status 1
Will be retried in 3s …
ERROR: Preparation failed: exit status 1
Will be retried in 3s …
ERROR: Job failed (system failure): exit status 1”

I think this started to happen with the new version of GitLab 14.0, I am wondering if this might have any impact on the exam evaluation.
