****SOLVED ****
After Hours Of Deleting Files From The Content File I Was Able To locate A file That Caused The Crash, Removed The File And From What I Can Tell It Was Possibly a Landscape Issue.
The Issue Has Not Replicated Since Removing The File.
Trying Hard To Think Of The Last Thing I Placed And Believe it was A Tree.
I Saved The Asset File In A Note Pad If Requested By Epic.
Thanks .
