Can't open illustration. Illegal or misplaced operator - cc
So this happened.

Cant open a file I've been working on for hours.
Been here:
"Can't Open the illustration. The illustration contains an illegal or misplaced operator"
Didn't work.
Been here:
How to recover a corrupted Illustrator (AI) File | DesignPoint
Seems too old & i cant work out any 'Content recovery mode' for my version of illy on the Creative Cloud - version - 2017 - 21.1.0
Can't find my preferences file. It's not where I'm told it should be.
Managed to do a simple reset of illy prefs but that didn't work.
Did quite a bit of searching for answers but kept going in circles, it seems like fixes are for earlier versions.
Don't know how to get access to this binary code people are editing, so I cant delete the " offending operator " ---> p '
Losing my marbles and need someone to explain like I'm 5, how to fix this. Step by step please.
Thanks!
