10.14.6 + OC not booting after latest Security Update?

NEVER MIND!! After 3 or 4 failed boots with no feedback, and a boot into Windows, it began working again after a full shutdown and restart...??!! Showing as build# 18G9323

I will reopen this thread should it not boot again after a shutdown.

My long running Hackintosh has stopped booting after latest security update (to fix zero-day vulnerabilities). I have tried resetting VRAM, recovery partition does not boot (forbidden logo), regular boot just shows black screen for a few seconds with no disk activity, then returns to OC boot screen :-(

Anyone else experience this, or have any ideas how to solve it? I am recreating a 10.14.6 installer USB on my other real 2013 iMac, and will attempt to install over the top?! That is my only option as far as I'm concerned?!
