Hardware Acceleration issue on my MacOS Sonoma 14.1

I was trying to use Udemy and it kept showing me a blank screen and I looked it up why and It said that it could be a hardware acceleration (I'm not sure)

I looked up post install guide on dortania the and I read this guide : https://dortania.github.io/OpenCore-Post-Install/universal/drm.html

but Im really confused so I followed a video guide :https://www.youtube.com/watch?v=OyFYBss5jDo&t=115s

I followed the guide but nothing worked for me (I'm still having the issue on Udemy)also it’s showing that Im still using an iMacPro when I click on "about this Mac"

and when I started the oc boot loader it showed me this error

NOTE: This version of ocvalidate is only compatible with OpenCore version 0.9.6!
