Cutting VUSB to 5V jumper trace too deep?

I use teensy 4.1s in a prodct of mine and need to cut the VUSB to 5V jumper.

This has worked fine for a couple of boards so far but the last one I just cut I fear may have damaged something.

How deep can one cut into the surface before the likelyhood of damage?

1.6mm I would guess unless it is a multilayer PCB.
 
Looking at the board again, the cut made is quite shallow so I suspect something else has gone wrong with this board.
