youtube block from an hour to an hour

I Have a problem.
My YouTube is available from an hour to an hour an then i cant even open he website.
i think its a sw.js problem, but i dont think so.

I’m asking if its repairable with a JSI (JavaScript Injection) or simply change some of the setting while i can use YouTube.

Before You Ask;

  1. My WiFi Its ok
  2. I’m not that guy that dont know how to startup a computer

About the Number 2, you can use technical language.

Can i have some help?
Thanks
