The game constantly crashes on my iPhone 11 Pro. During gameplay, the screen suddenly turns completely white and the game freezes or closes. After restarting the game, it only works for 2–3 minutes before the same problem happens again. I noticed it most often when receiving cards or merging harvested items. In those cases, my progress is often not saved. This issue happens every time and makes the game almost unplayable.

Steps to Reproduce:

1. Open Farm Merge Valley on an iPhone 11 Pro.
2. Play normally for 2–3 minutes.
3. Receive reward cards or merge harvested items.
4. The screen turns white, the game freezes or closes, and the progress is not saved.
