Osx won't boot with internal graphics enabled in BIOS

Hi there, I was hoping you fine people could help me.

I'm using a hackintosh build with a aorus z390 pro wifi, 32gb 2400mhz ram, msi rx 580 armor, and an i7 8700k.

Since updating clover I have not been able to able to boot into OSX with my internal graphics enabled in the BIOS. I am able to disable it and log in while connected to my rx580, but whenever I try to enable it I get a "couldnt allocate runtime area" error and can't login.

I don't know what has happened, I've been using my hackintosh with the igpu enabled for months.

I really need the igpu to work for hardware acceleration so if anyone has any suggestions it would help a lot.
