Can my Pixel 2 be saved?

The rear camera on the phone is defective. I got tired of living with it and tried to fix it. Despite following the ifixit steps, watching a YouTube teardown, and buying a heat gun, I wasn’t able to get the glass off without breaking a perfectly functional screen. I also had a little piece of copper shielding stick to the glass, and that’s the bit that I’m not sure about. How important is that? If I buy a replacement screen will I be able to get the phone working?
