I messed up :( Broke the Riser

My first PC build, got super excited to put this together and accidentally damaged the GPU riser 😭

I think I pulled on the GPU too hard without fully unlocking the latch and pulled the plastic bit off the pins. Seems pretty broken to me!

Is this something that anyone else has had happen? Is this something I can fix or will I need to buy a whole new case?

Thanks for any help, feeling real bad about this one 🙃
