Summary
UEFN Memory Leak Issue:
When launching UEFN, too much memory is being used by the application to where even running on the lowest scalability settings may crash the Editor when opening projects.
Before v39.30 it was stable (on Epic Settings), after v39.30, it was unstable (even on Low). Today’s update seems to be more stable (even with Epic) but has the same memory usage problem.

Steps to Reproduce
- Launch UEFN
- Memory will be used up by UEFN
- Open up a project
- Memory will still be used up and may crash UEFN
Expected Result
UEFN will use up as much memory as possible where it may end up crashing the editor when loading a project.
Observed Result
Editor seems to be more stable with the recent update, using ~8GB-11GB of memory, eventually dropping to around ~4GB
On the day of v39.30, UEFN was crashing.

Additional Notes
Sometimes opening another project while loaded in one already can crash the editor.
This issue started with the v39.30 update. The latest update for UEFN seems to be more stable (for now).
I’ve also had similar complaints by others who have better PC specs than me; including 128GB of RAM
