From looking at the error messages it seems possible that it is a graphics driver issue which I am in no way qualified to help you on, but you might check to make sure that the amdgpu driver is installed. Run pkg search amdgpu to see what is available. I have similar CPUs in other computers, but getting one running GhostBSD would be a significant effort so I'm not going to invest the effort if you have given up and moved on.
For Netflix and other DRM content I found the Brave browser to work well. When I first tried to play DRM content on Netflix it asked me if I wanted to install Widevine and once that was done I restarted Brave and watched Netflix.
Back when I was playing video games I would dual boot my laptop to WinXP for games and other Windows only software that I needed and into Ubuntu for everything else. When the laptop was 5 years old WinXP took forever to boot and could barely do anything useful but Ubuntu was still snappy so over the years I found myself abandoning the WinXP partition and running everything in Ubuntu. Getting Ubuntu to run well on the laptop took a lot of work and back in those days we would document that info for others that followed. Having WinXP to fall back on gave me the time I needed to get Ubuntu working on my laptop and me working on Ubuntu. Maybe you could dual boot as a solution to bridge the gap?
