Stickers are disappearing after Creation (iOS 17.5)

Hi Dev Team, Hope you are all having good day.

I have switched to iphone 15 Pro max everything is good except stickers are not populating as expected. The iphone is showing create sticker option at the bottom right corner but when I click on that it shows that sticker is being added but suddenly it has been disappearing. Don't know what to do in this, I remembered in my old iphone(XR) it was working and successfully created one sticker😅. Now I have only that sticker LOL! .... Not able to create new stickers!! Can you help me on this ? Also this is my first issue in apple community :)

Things I have tried:

1. 1. 1. Rebooted my phone
      2. Sign out and sign-in to apple id
      3. Googled everything but couldn't find appropriate solution🥲
