Trouble Upgrading from High Sierra - black screen after logo

Hi Everyone,

I've been trying to troubleshoot this and found a number of threads that seemed relevant to my issue, but none of the solutions I've tried have worked.

I've had High Sierra working near-perfectly for 2 years and decided to upgrade to Mojave. When booting the installer, the progress bar nearly reaches full, then the screen flashes and I'm left with a black screen. Additionally, my High Sierra install is no longer available as a boot option in Clover. Fortunately I do have a bootable backup - the drive it's on is very slow, but I can use it to access Clover Configurator and my EFI folder if needed.

Motherboard: Gigabyte Z370 Aorus Gaming WIFI
CPU: i7-8700k
GPU: Sapphire Pulse RX 580
RAM: Crucial Ballistix Sport AT 3200 MHz DDR4 DRAM 64GB (16x4)

This is what I get in verbose before the screen goes black:
