Running very poorly

I have a 2012 late iMac and installed OpenCore a couple years ago and last week I installed a post install root patch cause I never did before and it was running just a tad bit slow. I know I should have installed it right after, but I didn’t and now that I have installed the post install root patch my Mac is running like complete shit it was running completely fine before and now like stuff is freezing up. I’m getting beach balls or just straight up crashes everything. any advice
