Corsa D boot latch rattle, anyone fixed this?

My Corsa D has an annoying boot rattle that shows up every time I go over speed bumps. It’s coming from the boot lid area and I’m pretty sure it’s the latch or striker.

I’ve tried a bit of electrical tape on the metal loop which helped slightly, but it’s still there. Just wondering if anyone’s managed to sort this properly, was it a latch adjustment, the rubber bump stops, or something else simple?
