The chametz is sealed in the bag, so I would not be handling the actual chametz.
That’s called handling the chometz.
If you accidentally knocked over some chametz onto the floor in a store, would you leave it lying on the floor and make a Chillul Hashem?
If you accidentally turned a light off on Shabbos in a public place, can you turn it back on in order not to make a c”H?
If you accidentally knocked over a bottle of scotch in a store on Pesach, and the contents spilled, are you allowed to pay for it?
You wouldn’t be buying the Scotch, you’d be paying for the damage.
