Summary

After the 34.00 update, I try to launch a session with a large number of actors, after pressing the launch session button the editor does nothing for a while and then when it preparing to launch, it crashes. This is not the only problem. It also takes a lot longer to resave multiple assets in the content browser. Everything worked just fine before 34.00.

UEFN crashes for me too when loading a project but sometimes it doesn’t on the same project.
Looks like big projects now cause UEFN to crash more often than it did before the 34.00
