I have found a solution. A single asset has been corrupted, no idea why, but it was one that was placed in my scene. Here are my learnings in case anybody else stumbles upon the same problem.
- Make sure you have the engine debugging symbols installed, that way you can learn a bit more about the nature of the problem when the editor crashes.
- Delete your intermediary folder and see if the problem goes away (did not work for me but many people with similar problems suggested it.)
- Update your project to a newer version and see if the problem goes away (did not work for me but many people with similar problems suggested it.
- If that still does not help, open your project folder in explorer and start deleting your assets in a controlled fashion. So for example start by deleting half of your assets while keeping the other half and see what happens. Use the same method to narrow down to single assets. Using this method I could pinpoint the one (!) asset out of 15 000 that caused the issue.
I hope this is helpful to you!
I would like to say I am quite dissappointed about the fact that nobody every seems to respond on AnswerHub. My five questions since summer 2016 have not received a response and eventually I have returned to answer them myself. Maybe it is just me but honestly I have seen more badly formulated questions getting a response on the UE4 Answerhub. I would also think that I am an active member helping others so it kinda sucks that I never get back anything.
That was my last post on answerhub! Cheers.
