Help I've Lost all Hope, A script stopped working on my Player Character Prefab!

Hi Gamedevs, First time posting here.. so i ran out of search sentences to type on Google, so im here and very desperate. really hope someone replies. this is my first game project intended for android. so i have to scripts listed below both of which control various aspects of my character. the problem im facing is the player script i had which was working totally fine suddenly stopped working partially when the player dies and is instantiated by a game master script.. by partial i mean the ontrigger and collision functions and start functions work. but update has stopped working weirdly.. initially thought this was because of a crash so i deleted the cache items of the project and it rebuilt all but unfortunately it persists. what drives me crazy is that i keep reading the script over and over but cant see why my update just outright wont function even after saving it on the prefab! here is the script in question.

I have script that handles the camera zoom based on the player position so ill save your time by not posting it.. but any thing you need to understand whats wrong please tell me ! i desperate and i fear this project of more than 6 months may be a failure.
