Is this only happening on one project/puppet or all of them?
If you go to Window > History and go back a few steps before this happened, does it help?
Is your image really 4728 x 3123? That's pretty large - does making it smaller help?
Can you share your .puppet file via Dropbox / Google Drive / Creative Cloud link?
I had the same error and made my image smaller. After doing that it worked perfectly.
My file was even bigger 7324x1648.
So I had to experiment with sizes, but it solved the problem.
