Just updated to 4.7.4 from 4.7.3, and now when I press play, UE4 crashes every time. I’ve tried disconnecting events in blueprints, to make sure nothing is being called when game starts, but it still happens.
post-crash error report log shows “Access violation - code c0000005 (first/second chance not available)”.
project played fine in 4.7.3, and suddenly it crashes UE4. Is there a way to fix this?
Edit: I should also note that other projects seem to work fine. If I make a new project from vehicle template, crash does not occur.
Thanks! We’re looking into this now. When it crashed, did you submit crash report? Next time it crashes like this, please include a description and select Send. Thanks!
Additionally, please try disabling deferred dependency loading system (by overriding bDeferDependencyLoads in BaseEngine.ini to bDeferDependencyLoads=false). This will revert back to our old way of loading blueprints, and is more risky when it comes to cyclic dependencies, but it may unblock your project. Let me know what happens after trying that, as well. Thanks!
It looks like this crash is related to another we discovered in 4.7.4. (UE-13250) and a fix is on it’s way. In meantime, disabling deferred dependency loading system as described above should at least allow you to open project again. If you still experience this issue once fix has been released, please let us know. Thanks!
Hi ,
I have tried setting bDeferDependencyLoads=false, but crash still occurs when I press play button. I have submitted another error report referencing this question page.
Looks like same crash. Thanks for checking that out for me! We were able to track down problem, and fix is forthcoming. Please respond to this thread after it’s released if it doesn’t fix your project. You should return bDeferDependencyLoads to True before then. Thanks!
