"Magnesis Rune" Grab Object ability not working

Hey there.

I created a Zelda-like “Magnesis Rune” ability based off of this tutorial:

The issue is that after I use the ability for 5 or so seconds, the object suddenly stops moving. Once I release it, it falls to the ground (if mid-air). Once this occurs, I am no longer able to pick up or move any objects around the game.

I can’t see any reason why this is happening, and I’ve followed the tutorial very closely.

If I’ve missed something and anyone has a solution, any advice would be massively appreciated!!
