How to fix Twitch streams and Youtube videos/streams?(youtube is 50/50)

[asdasdasdasdasdasdddds]

Hi, I ran into a problem - the streams don't work on twitch, error 4000 is showing, the situation is better on YouTube, but there are still 50-50 errors that the video will either load normally or play with large lags, the sound plays normally, but the picture seems to be "5 fps" (the problem is not on the Internet, everything is ok in other browsers). Please tell me what the problem is and how to fix it. I tried a bunch of ways on the Internet, but nothing helped.
