After crash UE4 crashes opening any file I had open at time of crash

I made a button that set the updated component to null on the character movement component of an enemy. Upon pressing this button the game crashed. I had about 20 blueprints open on various things plenty unrelated to this crash.

Now when I start up UE4 it crashes if I try and open any window I had open at the time of the crash. Anyone have any suggestions?

Hi TinyAngryCrab,

Could you also post your dxdiag, .LOG., and .DMP files? Follow the link below for directions on how to find this info.

Ok. I’ve since reverted to a previous commit which allowed me to continue working. However attached are the dumps from the night that happened. The earliest dump is the original (completely reproduceable) crash from setting the players character movement updated component to null. The rest are from attempting to restart after that.
I have not been able to reproduce the second type of crash since reverting.

I’m glad you got your project working again. Thank you for you crash logs. We will continue to look into the issue and post back here if we find the cause.

Thanks,
TJ
