“Lost” a lot of apps on my iPhone!

I have iPhone 11. I upgraded to iOS 16 when it got launched, and it looked great for a while. But yesterday suddenly the first page on the Home Screen, with all my apps, was gone! They was on my phone, but not on the Home Screen. It was a lot of apps, because I have several folders sorted with a lot of different apps. So I had to again, use a lot of time, to sort and put back, all the different apps. Late last night, suddenly the first page in the Home Screen was back! I was so happy. And I started deleting, from the Home Screen, the apps that now was double. So…This morning, the whole page of all my apps was gone again! What is happening? I go crazy! Can support please check the IOS 16 for this bugs, and fix it! This has never happened before!
