I have tried running the GUI and it closed unexpectedly and without any error message. I thought it was an issue with the power controls, so I have turned off all power controls so the computer does not hibernate, or even turn off the screen.

As @nc50lc said, without any log/error message we only can guess or list all possible problems. Aside from debug.log, please check your journalctl and see any relevant message (such as I/O error, OOM killer is triggered or other hardware error). Usually i would this parameter,

Code:

sudo journalctl -p 3 -x -b -0

Where -p 3 show error message (use -p 4 to also see warning message), -x is extra message and -b -0 to show log from current boot.
