Can't load into the rink after the release of the Battle Pass

I ran into a problem when the battle pass was released in DotA, almost the next game doesn’t load me into the game several times, such cases before the battle pass were rare and connected with the Internet, now it’s only on a permanent basis, I have 4GB of RAM, more or less a good video card is not powerful , but not weak either, now everyone will say: change the PC, I would change it, but at the moment there is no way. In general, help me somehow, I have already tried everything, and the Internet and launch options and loading in the lobby and cleaning the PC to factory settings, reducing graphics, nothing helps .. in every LP game, without starting the rink, a new LP appears, before this didn't happen often.
