MacBook Air Mac Sequoia vs 15.1 What happened to Photos?

[BebeDahling]

I edited a photo of my dog when he passed away a few weeks ago. Now, every time I open Photos, it shows that photo and I can't get out of it. I refresh, I rebooted. Nada. I was going to delete and reinstall and cannot find it in the App Store. Any help would be greatly appreciated.P

What happens if you click on the back arrow to return to your photos. Then open and close the Photos app.

The back arrow is at the top near the zoom.
