Cant Left mouse click in playmode?

Basically I click play-mode to test my level i can move around fine but when i left click it pauses play-mode and takes me out of play-mode and both the play and pause button are both blue, like they have both been clicked on (but only one has)

Sorry if this doesn’t make sense.

If it pauses it is because you have an error. What is in the Console ?

Try this in the Update function :
