TASK SEQUENCE OS UPGRADE - IN PROGRESS 11142

[Markosss454]

I'm experiencing a high percentage of Task Sequence OS upgrade Stuck "In Progress".
Message ID 11142 ( This Task Sequence execution engine performed a system reboot initiated by an action).

A few machines in the same Device Collection did Upgrade successfully so I know the Task sequence works. Any idea on what I can check?

The computer system has updated to version 20H2, but the status in SCCM does not change. Status is "In Progress".

I think they are stuck in progress because they never continue, they've failed during/after the reboot, only digging into the smsts.log will you know for sure, but that should reveal the cause
