Blank Screen on Install

[Raptor2213]

Motherboard: Gigabyte x570 Aorus Ultra
CPU: AMD 5700G
GPU: AMD 5700G

Installing Proxmox for the first time, and getting a blank screen on install.
Tried with both 6.4-1 and 8.2-2.
Tried nomodeset with 8.2-2 - issue remains.

I managed tp get through the terminal install - only for it to immediately boot to a blank screen again.
I've checked to see if it's active on my network as well, but I'm not seeing it.
