Blueprint compiler crashes UE 4.12.1

Just updated UE4 Engine from 4.12 to 4.12.1.

Never had any problems with updating, but now…
Whenever i open up my project and then open
any BP and try compiling it; it just crashes, and other
stuff is also messed up like my AI i’ve written the AI character
can’t even move to the player character and before the update
it all worked fine and i had no problem.

Gotta say: bad updates can happen, but this is a shame.
Sorry

Hello,

Could you please post the callstack of the crash that you are experiencing? It will be displayed in the crash reporter window after the crash occurs.

Do you mean this window

Yeah, that’s the one. It looks like you don’t have the debugging symbols installed to display callstacks. I’m suspecting that this is related to a major crash that was introduced in 4.12.1, but has since been resolved. Try updating to 4.12.2 and seeing if you get the same crash.

I’m updating now
