Game Crashing when I load into the lobby

After pressing the continue button and entering the lobby, it kicks me out of the game without giving any error message. Yesterday I reinstalled the old driver version, and I could play ranked matches, but today I couldn't. Today I restarted the shader cache from AMD, and I could enter the lobby and play deathmatch, but as soon as I queued for ranked matches, it kicked me out. Now I'm back to square one; it kicks me out the moment I enter the lobby.
