Problem with gulp, npm, nodejs?

Question

linux

Actually, the problem is this.
After installing updates on the computer, gulp was updated. npm and nodejs (I won't say which).
And problems with local development of sites began.
It's just that everything works well on the local server, the pages open quickly, everything flies.
But after running gulp watch, everything is terribly stupid.
Previously, everything worked, I didn’t change anything in the tasks, but now the slightest change in the file and the page is updated in a cycle for a couple of minutes, then it only shows what has changed, although it may not show and you need to manually update and again wait a couple of minutes.
UPD: Even when you click on the link, there is no redirect, but only the page is updated, and it also takes a long time to update.
But if you open the link in a new window/new tab, it opens quickly.
From all browsers.

gulpfile.js is an old one under a spoiler, but quite a working one, on another machine everything works without problems.

I can’t understand at all who is stupid, who to kill, who to rearrange.
In fact, I have already tried to globally kill everyone, it does not help.
Kick at least in the right direction, well, it's unrealistic to work like that)))

What Linux do you have?
The easiest is to uninstall and reinstall gulp, npm and nodejs.
It is also interesting to know how you updated the system.
