Doesn't open site in OpenServer?

Question

open server

Help plz, I've been trying to figure out what's wrong for several days now and still nothing.
The essence of the problem is this: I install Wordpress on the locale (OpenServer), start making a template, and then after a certain amount of time (always in different ways from an hour to several hours), the site simply stops loading. The loading indicator in the browser is spinning and nothing - the site does not load.

I create a new domain, a new database, re-install the VP, install a template from the previous site, continue working on the template - after a couple of hours, the same thing happens again.

I tried to parse the error log, but did not understand anything.
