Son locked out phone, was working, now isn't, help!

My son accidentally locked out my iphoneXR, it said we could retry in 1 minute. I opened it up later and it was working fine, was able to use all the apps and made a phone call. A few hours later I tried to open up an app and it wasn't working and seemed stuck so I restarted the phone, put in my usual passcode and now all the apps aren't working, some actual pictures of the apps ie/ the photos, phone, messages etc. are missing from the home screen. I haven't backed it up recently so i really don't want to lose my photos of my kids. I thought it had backed up to my google photos but just checked that they are all gone. Would love any advice!

thanks!
