Ledge Climbing System guide

I think thats possibly just because you havent disabled the inputs that allow your char to move. The standard move fwd and right axis inputs. Put a branch there with a bool called “DisableMovement” and if true do nothing if false carry on as normal.
When the hang event runs then set disablemovement to true so the player cant move. And make a button to stop hanging. I think the OP uses crouch input.
