AR camera black after distribution throught testFlight

Hi, I packaged the AR template project as distribution mode to .ipa file in UE 5.0 on MacBook, and uploaded it to testflight then I installed it to my iPad, then I ran the project and also gave the project camera permission but the camera is black and cannot give any display. Could you tell me how to solve this issue?

Welcome to club! Problems with AR appear and disappear in different versions of the engine. I have not seen someone’s final solution, since problems occur in materials, incorrect conditions for checking devices, etc.
