Hello, wanted to stop by and let you know that the cause of the issue is the video card, if you put anything else,, I've seen posts with people using rx580 with no issues even and NVIDIA card just to through the install phase, it will work just fine.

I had this same issue, even formatted the machine thinking it was because of updating from high sierra (was stuck with nvidia), the first update this did not happen, because I updated with the nvidia card still installed, once catalina booted up, changed the video card with a RX5700XT and everything was working fine, the first update that I tried with the Radeon card, had the problem, tried multiple times, nothing worked, but I could boot to the macos partition normally, just not complete the update, hence the format of the machine.

Upon a fresh install got the same issue as you, which clearly showed me the update from high sierra was not the problem, popped a 1070 back in, completed the install, back to radeon, everything works fine.

still can't find a solution for this other than swapping cards for OS updates.

I've tried bootargs to wegnoegpu, removing weg, using only a DP monitor, removing the agmodpikera...

hope this helps.

CPU: AMD R7 2700x
RAM: 16GB Gskill 3200
Mobo: Asus TUF b450m Gaming
GPU: RX5700XT
Wifi: fenvi DW1560

10.15.5 has broken SMU Firmware for Navi Cards since Beta 1, just disable RadeonBoost kext.

Hey!, I don't have that kext in my system, in fact, had no idea about it until now, checking the config.plist from the dude starting the thread and seems like he doesn't have it either.

Same problem here as well. MSI RX 5700 Mech OC. x570 Aorus ultra.
So far I have tried Catalina 10.15.5 and 10.15.4 with no luck. grey crash screen after the first restart during install.
Mojave works fine-- except no graphics card support for navi cards. It shows up as 7MB graphics from my mobo... a little bit less than the 8GB VRAM I was hoping to have, heh

The next thing I'm planning to try is updating to the Opencore 0.5.9 beta... might just wait til it's official release on Monday.

Got it working! see this thread for the fix.

basically disable the dGPU after the first boot by adding the boot arg, then after the second boot, remove the boot arg, reinsert usb stick and continue from there

Just add -wegnoegpu into your bootflag into, yoiur config.plist and everything will be working like a charm. You must add it on second part of installer, and after that you can/should remove it, and yourt system will be ready to go.
