Sublime text 3 hangs when opening js files, how to solve?

Question

Sublime Text

Good afternoon! Please tell me, is Sublime text 3 when opening files, js hangs before opening, the larger the file, the longer it opens, for example, even if a js file of one page size already opens it is very problematic, and if you take a library to view, you have to wait a minute . I’ve installed it from scratch, the same problem, when the language backlight is turned off, it opens the rules, I found this problem, but how to solve what would be the backlight and work, for example, open it in a notepad, everything flies there.
