Freezing in hots

I have the following problem - in game in match x (this may be the first match in the session, maybe 4), there is a freeze (no response to mouse actions) for 4-5 seconds, and then a complete slide show follows - freeze-load-freeze-load.
I’ve tried many methods, re-read many tips and topics.
My characteristics:
ryzen 5 4600h, gtx 1660 ti, ssd, 16 gb ram.

What important have I tried:

1.Searching for similar problems on the forum (ru and eu) and on the Internet with a similar problem - a solution, as is clear, has not been found.
2.Reinstalling the game.
3.Optimize / reset settings in experience.
4.control panel geforce - force use gtx 1660ti
5.Reset and update IP and DNS

The main point was indicated, perhaps I forgot something. Tell me how to solve this problem and what you can try.

The problem cannot be with the internet connection - tried several options. There are no background apps. Drivers have been updated.

I don’t see this problem in other network games.

In msi, afterburner drawdown during dead hover for 5 seconds, and then everything is fine.

There are no problems with temperature.
