[Help] Tried to update to 2019-002-10.13.6 and can no longer boot

I'll get down to the brass tacks, I tried to take the latest HS update from the App Store (2019-002-10.13.6) and I can't boot my machine anymore from the boot drive.

Here's my parts:

Vanilla macOS Install

ASRock Z270 Killer SLI/ac

Intel Core i7-7700k

ASUS RoG GTX 1060 6GB

I knew I was on Clover v. 4871 before I updated, and just to do all the updating in one go, I updated Clover to 4910 in Clover configurator.

And now, I'm no longer able to boot. I used my recovery USB to boot to where I am now, and downgraded clover to 4870 from SourceForge, but that doesn't appear to work. I am able to boot clover just fine, but when I try to boot macOS, I just get a black screen.

Any other information or advice you could give me would be plenty helpful.

Thanks
