Compile Blueprint crash Editor 4.11p3/p4

Hi there

I got some problems with the Preview version. The Editor crash everytime i hit compile in my Character Blueprint.
When i create a new Variable and Compile, it works just fine, also when i Delete a Variable and hit Compile it works.
Without this, the Editor crash.

Here ist the last part of the Logfile.

Hello,

Could you please provide a screenshot of your blueprint?

If you are getting a Crash Reporter window, please provide your Machine ID from the window and ensure to hit Send on the crash report.

Hi

Here are 2 Screenshots from my Character Blueprint.
I don´t get a Crash Report Window, the Editor just close and that´s it.

When i rename the Variables it let me compile without problems, same when i create a new variable.

Have you been able to reproduce this issue in a clean project? If so, do you have any steps we can follow to reproduce this issue on our end?

Hi Sean,

i don´t create the Character Controller from scratch, but i Migrate the controler to a clean project and it also Crash the Editor.

Was it a Player Controller blueprint, or a Character blueprint that is causing the crash? Your original screenshots seem to indicate a character blueprint.

Also, you say when you delete a variable, it fixes the crash. Is it always a specific variable, or does it not matter which one you delete?

Finally, since this seems to be specific to a certain asset, could you please zip up your project and provide a link to Dropbox where I can download it? If you’d like to keep it private, you can PM me the link on the forums: https://forums.unrealengine.com/member.php?160394-Sean-Flint

Hi Sean,

It´s a Character Blueprint.
With the Variables it don´w matter witch one i delete, it works. Also when i create a new variable with the standard name, it works, but only one time. If i press compile a second time, without create or delete a variable it crashs the Editor.
Hope i explain it good enough, my english writing its not the best.

I send you a pm with my character bp.

Thank you for providing the project. I am currently spending time looking into this issue, and I will get back to you as soon as I have new information.

Do you remember any changes that you might have made to your blueprint before the crash started occurring?

I make no changes. The Blueprint works in 4.10.2 without any problems.
Thanks for look at it :wink:

Go ahead and try to recreate that same blueprint from scratch in the same project. It’s possible that the current blueprint became corrupted, so creating it from scratch would be a good way to test to see if this is the case.

I build my Character BP from scratch and it works until i link the AnimClass to it, then the Editor crash again when i hit compile. So i build the AnimBP from scratch to, as soon as i link the AnimBP to the CharacterBP the Editor Crash.
I don´t know if it is a bug or i did something wrong in the AnimBP.

When I reproduce the crash in your project, I am getting a Crash Reporter window appearing after the editor closes. Could you please double check to see if a Crash Reporter window is appearing on your end? I’d like to be able to compare the crash I am seeing to what you are seeing.

I don´t get the Crash Report Window, sorry.
I just get Preview 5 and nothing changes, the problem is still there.

Okay, thank you for checking and testing it in the newest version.

I am currently still investigating the cause of the crash, and I will respond with new information as soon as I have some.

Thanks Sean, i appreciate it

Hello,

I have reproduced the crash in your project, and have entered a bug report (UE-26742). Thank you for your report. I will provide updates on this issue as they become available.

Have a great day
