Hi!

UE4 keeps crashing on startup. Worked just fine yesterday.

Here’s what I get as a crash report:

Access violation - code c0000005 (first/second chance not available)

Hey Fryderider-

What were you last working on before this error started occurring? Based on the callstack it looks like it may be related to a child actor component. If you’ve added a child actor component to a blueprint recently, you can remove the .uasset from the Content folder. This should allow the project to open.

Thanks for your reply .

I created two Blueprints, one of them contained a Child Actor Component. But I don’t know how that would cause a crash.

4

There is a known issue in 4.14 where child actor components in blueprints causes crashes. You can find more info on this issue here: Unreal Engine Issues and Bug Tracker (UE-39323) . Removing/recreating the blueprint with the child actor component should allow the project to open normally.

Cheers
