Hi!
Can you provide the output from dmesg after you've loaded amdgpu.ko, as 
well as Xorg.log from when X is failing, and `pciconf -lv | grep -A 4 vga` .
I think you need to upgrade to FreeBSD 13-current to get support for 
Ryzen-3 3200G, but I know more once you've provided the details I asked for.
Regards
