Intune Autopilot stuck on account setup (Hybrid)

We had the same issue with a native AAD device. Stopped at Security Policies (Identifyting) for a long time (15-20min). We still have an open ticket with MS about it, but our hypothesis is that it has to do with the schedule tasks not running due to the time being incorrect/changing during autopilot. One thing you can try is what is noted on the Autopilot known issues thread:
