I tried both methods and yet no luck.
If it is a bug, you can upgrade 10.14.5 beta2 AMD kexts and frameworks to 10.14.4 manually.
Backup below kexts and bundles
400520

Then install above kexts and bundles from Mojave 10.14.5 beta 2 to Mojave 10.14.4 /System/Library/Extensions/

Backup below frameworks
400522

Then copy and replace above frameworks from Mojave 10.14.5 beta 2 to Mojave 10.14.4 /System/Library/PrivateFrameworks/

Work fine with Ryzen3 2200G + RX560 on 10.14.4 (recently not able upgrade to 10.14.5).

What’s the new values for graphics device policy? I have upgraded to b2 and my system is booting to black screen.

Now that RX 580 is natively supported in the latest beta build, would it cause an issue if I switched back to iMac14,2 or iMac15,1 profile? These two profiles matches the hardware that I have. I would still keep iGPU disabled.

You can make a backup of the efi folder and try. Please report your findings.
