It is not clear to me if you updated Core to 13.3-RELEASE. Please do know you cannot install Core 13.3-RELEASE through the regular updater. You need to do that manually. THIS LINK will help you get going.
Would you mind describing the process for the update to Scale?
I’m a newbie and this is all beyond my pay grade (I don’t see a menu option for this upgrade).
Thanks in advance.
