FPS hands disapears oddly?

Okay, i honestly dont know how to explain this.

Im working on a FPS player character, and it is a very odd thing happening.
When i am looking in specific agles with the player camera (the head) right then the fps hands model becomes invisible?

The shadow on the ground is stil there, but the model it self is just not there? and its always the same angles it disapears in?

i have never encounted anything like this?
If anyone else had and found a solution for it, please give me a heads up!

Deleting the PhyssicsAsset made it work thanks!
