Pilot 95S Elite Repairable?

[Atomicpink]

Hi, I new to fountain pens and I think I broke my Pilot 95S Elite by accidentally putting in a platinum cartridge in. Once I realized my mistake, I removed it and put in a Pilot cartridge. However, at that point, a black piece of plastic fell out from inside the pen. I think it is part of the feed?

Can this pen be saved/repaired?
I'm so sad, I love this pen.
