Remove camera raw filter

Hi everyone!

Apologies, I am a new Adobe user, so I am not sure if my issue can be fixed.

I am currently working on a publication using Indesign and am editing my images directly from Indesign to Photoshop. I have just edited an image as black and white using the camera raw filter and saved it, but it has saved the filter onto my original file too. Is there a way to undo this? I am using a Macbook Air, and 2023 Photoshop & Indesign.

Thanks 🙂
