I had the same problem,Task Manager and "Close" FIVE M, keep re-opening FIVE M and choose any server excluding the one of 64 players, also press the middle button between "CTRL" N "ALT" drag mouse icon to your selection. I hope this helps!

Examples: under Disruptive Behavior= VOIP SPAM(meaning)? , HORN Spam(meaning)? .etc.
