While playing on the community servers (in this case I was the host), a person came to me, when we selected characters, I started the match, but he somehow left the lobby, and thus I was left alone, and not in the lobby, but in the preparation for the battle.
After loading the map, the camera got stuck in one place and the game "froze?" That is, not Esc, not other keys did not work, and I simply ended the process with Alt+f4.

Thanks for wasting your time reading my "manual?(no)", I just wanted to share this strange error (and discussions don't allow that), anyway thanks for being here, have a good day.
