Crashing when opening any blueprint in my project, even new ones

anonymous_user_03be5e5b · November 27, 2016, 4:20pm

I am crashing when opening any blueprint in my project. I tried removing a bunch to see if one in particular is causing it but I can’t narrow it down. I tried migrating my content into a fresh project and it still crashes. I can’t even right click on some blueprints in the content browser without crashing despite being fully functional when I copied them to backup.

Weird thing is that the crash didn’t start until I closed the editor. I made 2 full project backups during a work session, and both of them are crashing in the same manner.

Logs aren’t giving much information:

Did you build from source or using the binaries from the launcher?

anonymous_user_03be5e5b · November 27, 2016, 8:58pm

My project is all blueprint but I made a c++ project to try and get more information on the crash.

emretanirgan · November 28, 2016, 1:25am

I’m getting a similar crash after upgrading to 4.14 and working on my project a bit, I suspected that it’s something with the Child Actor Component and I see several people on here having issues like this. Hope Epic can resolve this soon!

anonymous_user_03be5e5b · November 28, 2016, 2:09am

Yeah I just narrowed it down to that as well. I re-did all my work and closed the editor every task I finished. I was able to ruin the project again after adding a child actor to a blueprint using the Add Component menu. The blueprint it exists in also sets up a reference variable and fires an event from event graph that exist in the child actor.

I can’t repro this in a new project.

Sean_L · December 1, 2016, 2:31pm

Hey everyone,

Do any of you have a test project that this crash is occurring in that you’d be able to share? You can upload it to Dropbox or Google Drive and pm me a link on the forums: https://forums.unrealengine.com/member.php?160394-Sean-Flint

As you have been unable to reproduce the crash in a clean project, this is the best course of action to hopefully diagnose the issue.

Thanks!

anonymous_user_03be5e5b · December 1, 2016, 5:24pm

I don’t have permission to send private messages. Any other way I can pass it on?

Sean_L · December 2, 2016, 6:36pm

Were you logged in to the forums at the time? PM’s are our main form of communication for private project sharing.

anonymous_user_03be5e5b · December 2, 2016, 7:02pm

Yes, I am logged in. Is there an action I need to complete before I can send private messages?

emretanirgan · December 4, 2016, 10:37pm

By the way, I made a few comments on this question as well, and I’m not 100% sure but I think the issues might be related. I can zip up my project and upload it if you think it’d still be helpful. I thought this (UE-38690) would maybe fix it, but I built the engine from source with that commit in it and I’m getting the same crash again.

Sean_L · December 5, 2016, 2:44pm

When you’re making a comment here on Answerhub, you should see an arrow underneath the blue ‘Comment’ button that says Viewable by all users. If you click that dropdown and select Moderators, you should be able to provide the link in a way that only moderators would be able to see. So you’re welcome to give that a try if you can’t get PM’s to work.

Sean_L · December 5, 2016, 4:29pm

Hey everyone,

I’ve recently entered a ticket for an issue that I think could be similar to what you’re experiencing. Take a look at the link below and let me know if it sounds similar to what you’re seeing:

Have a great day

emretanirgan · December 6, 2016, 7:51pm

This sounds similar to what I’m seeing, except in my case I’m casting the Parent’s Child Actor Component to the Child Class. The callstack seems very similar so I think there’s a good chance my issue is related to this one as well.

Sean_L · December 6, 2016, 9:19pm

Okay, there are a couple of repros for this issue, so it’s likely that the issues are related. I’d recommend merging the fix into your build (if you’re using source). If not, let me know if you still see the issue in 4.15.

Thanks!

emretanirgan · December 6, 2016, 10:48pm

Ok, I’ll try building from source and give it a shot. There’s no link to the fix commit though so I can’t see whether it has already been merged into 4.14 or master. Is this fix already in one of those two branches?

Sean_L · December 9, 2016, 6:20pm

Ah, if there’s no link to the commit, the fix was likely merged into one of our internal branches, which means you’ll have to wait until the merge into main takes place. Once this occurs, the ticket should be automatically updated with the new CL to grab from Github.

Sorry about that I didn’t notice that was the case with this one.
