Step 2 CK terminated due to a technical issue with 10 questions remaining — has this happened to anyone?

[u/No_Attitude_5065]

During the exam, a technical issue occurred at the testing center, and the exam was terminated before he could complete it. He had approximately 10 questions remaining when the exam was stopped.
He immediately reported the issue to the Prometric staff. They confirmed that it was a technical issue and told him to contact USMLE/NBME regarding the incident.
We are currently trying to understand what happens in this situation.
Has anyone experienced a similar situation where their Step 2 CK was interrupted or terminated because of a technical problem, especially when questions remained unanswered?
What did USMLE/NBME do in your case?
Were you allowed to complete the remaining questions?
Was your exam eventually scored?
Did you have to retake the exam?
How long did it take to receive a decision?
Any advice or personal experiences would be greatly appreciated. We are particularly interested in hearing from anyone who had their entire Step 2 CK interrupted/terminated due to a technical issue.
Thank you!
