Editor crashing whenever I try opening a Character Blueprint

Development Programming & Scripting Blueprint

So I’ve come across a rather strange problem.
For some reason that I do not understand, one of my AI’s just stop working, and crashed the editor whenever I tried to load it. This crash occurred if the character was on the map, if I tried viewing their blueprint, and even if I tried viewing the AI Controller.

My first workaround was to try using an older version of the character, but the crashing persisted.
I even tried remaking the AI from scratch, but still, nothing but crashes.

I noticed something odd as well. After these crashes started happening, any actor that I made afterward would also crash the editor (It would work for a while, until I re-opened the project, only for the actor to no longer work.
I even made an actor whose only function was to receive damage, yet even that still crashed it.

From what it looks like, I may have to restart my project from scratch because of this.

Ive had an issue where I need to open a specific BP or any BP I open will immediately crash, to explain my issue and perhaps help you to locate yours, I had a circular reference and for some reason it was causing the BPs to not compile correctly.

[2017.01.28-16.17.37:942][  0]LogUObjectGlobals:Warning: Failed to find object 'Class None.'

I see this in your code at line 275 and perhaps you are not getting a correct reference in a BP or a class is missing, it may not have been deleted just that the compile order isnt correct causing it to die.

Now this is just a guess but I would suggest seeing if there is a BP you can open that somehow fixes the crash and if there isnt, if you could remove the cause of the problems which seems to be Character BP with the editor off and replace it back in while the editor is running and see if you can modify the cause of the error before construction is ran. There used to be a way to turn off construction script from running from outside of BP but that doesnt seem to be available.

Anyway sorry I couldnt offer more specific help but I hope this does :slight_smile:

Update:
The character controller is now crashing as well. It wasn’t before, and I haven’t made any changes to the project.

Hey FalexAye,

I have a couple of questions:

  • Are you getting a crash reporter window? If so please provide your Machine Id and ensure to hit Send & Close on the report.
  • Have you tested this in 4.15? If not, please upgrade a copy of your project to 4.15 to see if this issue occurs there as well.

Thanks
