How to find the cause of Chrome brakes on YouTube and VK?

Question

YouTube

Hell, Chrome slows down on YouTube and VK where there are fields for entering text. For example, the search string. It is almost impossible to communicate in VK, when you enter a character, the page freezes for 2-3 seconds.

I've tried uninstalling extensions one at a time, but the problem persists. Cleared cookies and cache.
Windows 10 Pro 2004.
Where to dig?
