Play button not playing the game. BIG PROBLEM(Solved)

Today i loaded my project and nothing worked. the only thing i changed without testing the day before was adding a bool to a script that changed the players color.

Today when i hit play all of the codes run through their start functions then stop. the only script that is working is the color changer. everything else seems frozen in time.

I have tried disabling all the scripts except game controller and the problem persists.

I have looked over my code for hours and haven't found any issues with it. everything just stops for no reason. Please help.

UPDATE: more debugging has found that the update sections are only called once.

Game controller script.
