OC 0.5.8 Catalina system crash after installation on first boot

[Hackindan]

Hi guys,

After loading 10.15.4 on to my newly formatted APFS partition, the computer restarted and proceeded to go into the first time boot.

Just before the usual “welcome to Catalina” this screen popped up.

Any idea how to fix or what the cause could be?

I am running AMD Ryzen 3700x, Msi B450m Mortar Max, Msi RX5700.

Any help is greatly appreciated

If you can try replace yours GPU on other model, or edit config.plist, and add -wegnoegpu bootflag.
I had the same issue, and for me helped replacing GPU, and after that everything was OK.
I think this is common problem with RX5700/5700XT graphics card :/

Thx fntzzz, your suggestion to this thread allowed me to continue with my install. I've also updated my issue with more details here.

you add agdpmod=pikera ? in the boot arg on the NVRAM? is required for the AMD 5000 series graphics!!
