I have added the 756m line but this hasnt helped, ive then uninstalled and reinstalled but it still wont open.

Answer 1

I assume you have one or more user-defined palette sections with very large or many, many image templates.

To solve your problem, either assign even more memory to yEd or delete your yEd profile directory. This latter approach will reset yEd to its factory defaults (and delete all your custom settings.) Re-install does not help, because it does not delete the yEd profile directory.

I have deleted the yed profile directory which contained the images and removed my saves to my google drive.

Any ideas what else to do?

Answer 2

As of yEd 3.11.1, OutOfMemoryErrors while loading palette sections no longer crash yEd. Instead, yEd will ignore the elements in the problematic palette section.
