uBlock origin is the same code on mine or yours machine. It does not need a graphics card, nor uses some particular instuctions of the CPU.
On Firefox Stable on Flathub at the time of writing, with default settings and default lists, it will work as expected on Youtube.
Google does not always provide the same Youtube code/challenges to you and me. That's what A/B testing is about.
Is uBlock Origin working for you specifically, enabling it alone with no other add-on?
