Hi Daren,
sorry, i cannot see your screenshots, but unfortunately AMD Radeon Pro 560 is a Polaris GPU.
AMD Polaris and Intel GPUs are not supported anymore in new OctaneX PR12/13 for macOS 12 Monterey - there were some Apple Metal driver related issues.
You should need to go back to Big Sur 11.6.2, with OctaneX PR11, or you need a Vega, Navi or Big Navi GPU with macOS 12 Monterey, via Thunderbolt 3 port + eGPU box.
ciao,
Beppe
