Exception_access_violation

Hello !

Since this evening, I can’t open blueprints that has my controller or my main pawn (I unable to find). Each time there is an “Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x00000010”, and Unreal crashes. (Or unreal-cmd when I try to launch it)
All was fine, then I just unchecked some “reliable” checkbox of 2~3 CustomEvent and it was brocken.
I tried to restart my computer and use backup file from this morning but it didn’t work.

It seems that even the BP editor doesn’t open (I don’t see the loading bar)
And all BP are “brocken”, but I still can open materials, meshs and textures.

The log from where it’s not usual : http://pastebin.com/tAvGZZn7

I’m using UE 4.12 from GitHub, VS2015 (obviously) And running on Windows 7 64bits.
I can add more info if you need !

I tried to delete “Binaries”, “Build”, “DerivedDataCache”, “Intermediate” and “Saved”, and generate them again (with VS then Project Launcher) but still the same trouble …

I don’t know if it’s a good thing, but it’s always the same addr : 0x00000010, each time I try to compile.

So after some new try this morning, it appears that it’s because of Some “Reliable” checkbox on networking events (run on server/client) I unchecked that the engine crash. Each BP referencing my controller can’t be opened and the editor crash. And it’s always the 0x00000010 address the problem.

Please, can someone help me !!! I can’t work cause of this !

Strange thing : All the backup files I tried didn’t repair it :frowning:

So I give up and will remake my controller, this way it will be optimised thanks to what I learnt since I use UE4 :slight_smile:
