I am having issues ever since i installed an inductive sensor on my board. Everything seems to work fine, apart from my X STOP.

Below is the report from M119, keep in mine, i am not touching, or going near my X STOP trigger. I have replaced the trigger switch, i have made sure all connections are good and seated, i have ensured everything is fixed down properly.

Reporting endstop status

Update. M119 reports triggered even when the X stop is unplugged from the board.

Most endstops are configured so that when they are unplugged they are triggered. How else would you know your endstop has been unplugged?

While relevant, this isn't exactly helpful. I'm thinking there is something wrong with the pins on the board. Is there a way to reconfigure the code so i can use different unused pins somewhere for my X trigger?

After more investigation, my Y-stop is now always open... As is my Z-stop

you need to edit the pins.h or specific board pins.h to move the endstops to a new pin. Any unused digital IO line can be used

Do you have a guide, or can you run me through how to do this?

you haven't told us what firmware you are running

eg If a recent version of marlin

edit pins_RAMPS.h

In it you will find

#define X_MIN_PIN           3
#ifndef X_MAX_PIN
  #define X_MAX_PIN         2
#endif
#define Y_MIN_PIN          14
#define Y_MAX_PIN          15
#define Z_MIN_PIN          18
#define Z_MAX_PIN          19

Change the number to what ever pins you want (Use D(igital) pin names)

See the following image for a list of all pins

I purchased a new ramps board, same issue. I moved the Z-min to D11 which triggered correctly on the Z, but I'm still having the same issue. Please, someone must have a solution here?!

Perhaps you don't have the pullup resistors on the endstop pins enabled in the firmware?
