Black Screen after Apple Logo on OC 0.5.9 and 10.15.5

Hi all, I have been struggling trying to figure what's going for a few days now.

Specs: 9900k, Z390 Designare, 5700 XT Sapphire Pulse

OC 0.5.9 and 10.15.5

I have been running this 5700 xt for a few months now from 10.15.2 until 10.15.4 with OC 0.5.7 to 0.5.8. Recently with the update to 10.15.5, my screen now keeps booting into black screen after apple logo.

I'm running dual boot so when I try to boot into windows, the gpu works perfectly fine, running games for hours with no problem. So the gpu is fine. I even borrowed my friend's radeon VII to test to see if the update broke my EFI but with the Radeon VII, dual 4k monitors worked.

I tried to remove whatevergreen kext and it actually booted into the OS but only one monitor recognized and I can't watch any netflix on safari anymore. The computer still recognize the 5700 xt in system info.

I have already tried with and without agdpmod=pikera with no luck.

Maybe something is wrong with the platform ID and Framebuffer? This is the screen with no whatevergreen that I can boot my mac into.
