[Crash] 4.4.1 Editor crashes

Development Programming & Scripting
1

Hi Guys,

I had a project which I was working on in 4.3.1 which I upgraded to 4.4.0 and then to 4.4.1. This involved a blackboard/behavior tree based AI system.

Everything was fine till I was working with unreal 4.4.0. The minute I upgraded to 4.4.1, everything started to wig out, and in a really bad way. Even a small recompile of any blueprint crashes the editor to oblivion. Forget about adding new nodes or anything; if I as much as connect and disconnect existing nodes and recompile, it crashes. If I do a play in editor, and then stop it, it crashes. I have submitted a bunch of error reports to you guys already via the automated error submitting dialog box you have; if you need me to submit a log here, I will do so. Can you guys tell me what the problem could be?

BTW, I have Unreal 4.2.1 and Unreal 4.3.1 also installed.

Hey mdhananjay,

Can you also give me your dxdiag? It would also help if you could tell me your project’s name or what text you put in the crash reporter so I can find your crash reports.

Hi Jonathan,

The project(s) you should most likely look for are AOUNL or UNL, usually with messages like “Crashed when re-compiling blueprint” or “Crashed when exiting PIE mode”. Sorry I don’t remember the messages exactly.

Ok so I opened DxDiag and did a save all information; I suppose that’s what you wanted. If it’s something else, please let me know.

Also, I know typing mdhananjay can be a handful so, for future reference, my first name’s mukund :slight_smile:

Hey Jonathan,

Thanks for the info, it really had me worried, because quite a lot of work was/is stuck in there. Two questions:

  1. Is there some way to port it over to 4.3.1, or to do that will I have to start over?
  2. What was the cause of the crash? Is it some hardware related issue? Or are you guys still investigating the cause?

Thanks again.

Hey Mukund,

After comparing the crash reports, it seems you’re experiencing the same issue as this user. It’s a known issue and we’re working on creating a fix. I’ll post in this thread again when I know more.

Thanks,

Jonathan

  1. You might have a backup of the project in C:/Users/[Username]/Documents/Unreal Projects/[ProjectName]/Saved/Backups . If so, that could help you recover data. If, when you converted to 4.4.1, you picked ‘Open a Copy’, then you should still have a 4.4.0 copy on your computer that works fine. If you picked ‘Convert In Place’, then you probably won’t have a copy there and will have to rely on the Backup.

If those don’t help, you might have to wait until we can write and implement a fix that fixes your project.

  1. Investigation is ongoing, but I believe the issue is caused by an error in blueprint code when the blueprint is converted to 4.4.1.
