I doubt the insert is ‘defective’ – all it is is a piece of material with a cut line in it that you cut on your own saw.

a few thoughts:

1. +1 to Jims idea, if your cut wasn’t clean, you may have some burr on the edges of the newly cut slot – use a file to lightly debur those corners and it may remove the excess noise.

2. if #1 didn’t work, I would turn off the saw – unplu it from the electic outlet, raise the blade, and turn it by hand – slowly, see if you can fine any specific teeth on the saw that rub against the insert and cause a scratching noise, if these is ALL the teeth then your cut was off somehow (was the blade at exact 90 when you cut it? is it still at exact 90?), if it’s just some of the teeth than you have a bent blade or your arbor is not running true (or the blade is not sitting properly on the arbor)- check for those
