What I meant was not to mean that you created the problem, and I believe you, of course, I only faced such problems while entering the game as usual, I just asked what caused it and how to solve it. (I could not tamper with the settings of the game in any way, I did not mess with the files, I did not install anything extra)
Not with settings of the game, but OS settings. Sometimes AV can cause different problems. Try to disable, if you use any. And if you don't use, then install Free BitDefender/Malwarebytes and scan your system.
If you have friend with laptop, or maybe you have laptop, then test game from different internet connections.
