Thanks Alexander - my system has the latest and greatest of everything so I don't believe I have a memory issue.
A shout out to Phil Read (he helped me when I was deciding to purchase Enscape)
I unchecked the RTX Raytracing and was able to render at max resolution (8000 ppi) without any trouble. I sent this information along with my log files to Enscape.
Hope this fix can work for other people.
