OpenCore-Patcher metallib installation failed on Sequoia 15.3.1

I installed macos Sequoia 15.3.1 on my 2012 macbook pro a1286 i7 16gb, so far everything is ok, I start OpenCore-patcher but I can't finish the Post-install root patch. I start the Metallib download and at the end of the download it says installation failed, and it doesn't apply any patches, the hd4000 video card doesn't work and neither does the wifi
