Gives an error when trying to enter the game

I go to the game on the Steam platform. The game logs in and starts downloading shaders after them asks to click the mouse to continue, after that a long download with a black screen begins and it gives an error (connection time to the server has expired (code: net)). I tried to solve this problem with support, but the instructions they provided to solve the problem did not help (they asked me to clear the boot cache, then run the PC, go back into Steam, turn off the modem for 3-4 minutes and try to enter the game again). It was not possible to find a solution to this problem and they redirected me here with a link and asked me to describe their problem here. I've already tried many ways presented on the Internet (checked files, deleted and re-downloaded the game), but everything is useless. I hope there will be a solution
