Physics Handle Grab Object Exploit

I used a physics handle to grab objects.In a first person game.But the thing is,the character can put the object he is holding under him while holding it and get higher on the level.I made a clamper that clamps the rotation of the cameras pitch,but It is no use,this time he can just go up to a wall and do it there.

I want to make sure the players can’t glitch through levels.

I solved it.I used a Switch that uses ECollisionChannel.I got the Enum state from a down trace I made to check if I’m falling or not(I know there is IsFalling state on movement components).I put the switch right after Input Jump node.

This is how I’ve done it.
I forgot to mention that I also used a branch for the physics object part of the switch.

do you have this lag? and how do you fix it?
