Problem with character control in a new level

I have 2 levels in my game. When I’m in the startup level (at game start) the character responds to all movement inputs (WASD, arrows, and mouse (for turning/rotating). But, when I teleport to (open…not level streaming) the new level, WASD and arrow keys still work, but there is no mouse control (mouse movement does not rotate the character). I’m not changing anything in the character or character movement details from one level to the next. What am I doing wrong or not doing correctly? I’ve scoured Answer Hub and didn’t find anything that addresses (or fixes) my issue. Please HELP!!!
