You have started a new conversation for everyone to see, so hopefully people will jump in an advise some things to try.
As Bailey mentions, try a couple of Hard Restarts. Press volume up, then down, then press and hold the power button till you see the Apple logo. If your device has a home button, hold down the button and power button together till you see the Apple logo.
If that doesn’t help try logging out of iCloud and then log back in and let your device pull everything back down from the cloud. That might sort your user photos out.
You can also try reinstalling the iOS. There’s a guide pinned at the top of this forum, on the first page.
Failing all that, there is a good chance we will see a new beta today so you can install that to see if it fixes anything. Then try the steps above maybe.
