EliteBook 840 G5 and G6 stuck on Sure Start

[bcls]

We have several HP EliteBook's 840 G5 and G6 that get stuck on Sure Start after installing Windows updates. They are running Windows 10 x64 - 1809 and the last time it happens was after installing the "2019-12 Cumulative Update for Windows 10 Version 1809 for x64-based Systems (KB4530715)".

We only see this behavior on systems running Windows 10 Version 1809, the ones that are on 1803 don't have this issue. 

We are deploying the  updates via SCCM and in the logs we see that the update installed correctly, but after a reboot they get stuck on the Sure Start screen. The only way to recover is to boot in Safe Mode and then the last installed update is removed automaticly. Afterwards we can install the same update without any issue.

update: it doesn't seem to be related to a specific update, because we see the same behavior after installing the cumulative update of january: KB4534273

I would like to state that we have applied the '2020-01 Cumulative Update for Windows 10 Version 1803 for x64-based Systems (KB4534293)' update to 700 HP 840 G5's and to date 60 of them have failed with the same error and get stuck on the Sure Start only to be resolved by going into a repair and safe mode to roll back the update. 

We have ensured that the laptops have the latest applicable 'Servicing Stack' installed, '2019-11 Servicing Stack Update for Windows 10 Version 1803 for x64-based Systems (KB4523203)'.

We cant afford for this many units to be effected when monthly Windows 10 updates are installed. Any assistance would be very welcome.
