When a CBS.log gets to a certain size, Windows archives it and starts a new CBS.log, occasionally it happens at an inconvenient moment. Such was the case this time.
There's a few things being flagged in your persist logs that need patching, but to get them I'm going to need to update my WS2019 VM a couple of times, as they're from different updates, so it's gonna take me a while.
I'll get back to you ASAP, but it may not be tonight as I've got some other stuff I need to deal with as well.
