Photos lost after a restore

I went to London today and took a bunch of photos and videos and I was somehow on iOS 27 beta so I wanted to go back but I didn't realise my photos didn't sync to my iCloud. So when I restored my iPhone to iOS 26 using an old backup all my photos have disappeared and im just wondering if theres any hope out there, if anyone could help me see if theres something I could do to get any of those photos back
