Game crashes after selection screen, when the game loads. Specifically and specially on EUNE.

Last month I had several matches where, during ranked play, got kicked out aka disconnected when the match started.

Usually THE WHOLE GAME FREEZES on the VIDEO and you have to literally restart the pc. AFTER THAT, YOU RELOG AND YOU GET A BLACK SCREEN, AND/OR GAME MENU DISABLED. IF YOU TRY OTHER SERVERS IT WORKS NORMALLY. BUT NOT ON EUNE. EVERY TIME. AFTERWARDS, THE GAME CAN BE REINSTALLED, TROUBLESHOOTED AND EVEN HEXTECH REPAIRED AND NOTHING HAPPENS. SEVERAL TIMES I EVEN REINSTALLED EVERYTHING. EVEN MY WINDOWS. I POSTED THIS PROBLEM LITERALLY EVERYWHERE, EXCEPT HERE, BUT NO ONE DOES ANYTHING ABOUT IT.
