Super Slow autocomplete for Javascript

Hello,

I am already desperate. It's amazing how a simple document.......querySelector, takes like a minute. I've been like this for a year with this crap, which makes me in my work much slower.

Is there any solution for this, I have already tried clearing the cache and restarting. Do I have to buy the NASA computer?

If I don't find any solution I'm going to Visual Studio Code to never come back and it's free, although for me money is the least important thing, the only thing I want is to work comfortably.
