Help with and error

So I just started my 1st chapter on a new story and I tried to save it and an error popped up saying unable to parse
back up your script
if your chapter is 8k+ lines it may be too large to save.
try reducing the length of your chapter
error unknown
But all I have is where you can create one character and a little but of the narrator talking… its on line 848… And I have more then one character for the reader to create… Dose any one know whats going on?
