TLS dosen't work at all now and can't downgrade

I looked on internet that Macbook pro 15' (HDD) can support macos Sequoia, after that i could not open any websites on safari and appstore just crahses, even tough i was connected by a cable, maybe i did something wrong and now its dead? I reinstalled root patches tons of times, and reinstalled open core too, if i try to install other macos i get this error "An error occured while extracting the macOS installer. Could be due to a corrupted installer" I need help!
