Can Play and Eject but Unreal crashes upon trying to look around as the pawn

Something (part of my code?) is suddenly causing a crash in Unreal. I’ve made sure the pawn_BP has its PhysicsHandle component. The code compiles OK in Unreal with no visible errors (builds OK in VS as well with no errors). Now, if I press Play the game launches, and I can eject and fly around if I want to - but as soon as I possess again and try to move or look around, Unreal crashes immediately. I have had zero crashes up until this point.

VS 15.95
Unreal 4.19.2

Any error from VS console? Also warnings or some other stuff?
Also if the compiler said there is an error and then compile, there are some?
Code looks good excpet for that const that u need to put at the end of the method

FHitResult GetFirstPhysicsBodyInReach() const;

and also this one

FHitResult UGrabber::GetFirstPhysicsBodyInReach() const

Try it out! Nothing wrong

Sorry I was totally wrong. Const goes at the start of the line!
I just got an error due to this stupid problem :smiley:

Thanks for the suggestions. I’ll try them next chance I get.

I have same problem,could you solve the problem?
