Issues with Seniquoa

Apologies if I spelt that wrong. Anyways, I updated to the beta via system prefrences, and it's running like trash- I have a macbook pro 2017, and I cannot use OCLP to patch it or fix the lagginess. Furthermore, I don't have access to internet anymore- what do I do? I tried to reinstall old sonoma, but it did not work- says I can't downgrade. What should I do? Is my macbook now obselete?
