App rejected by apple review team

My flutter iOS app is rejected 4th time for below reason. Tested the app on real device including iPad Air 5th generation and it's working fine for me. But apple is replying me with the same reason again. Please help.

Thank you for your post and appeal. We are investigation and someone from the App Review Board will contact you in App Store Connect to provide further assistance. If you continue to experience issues during review, please contact us.

My team is experiencing the same issue, we have an app update which has been rejected for the exact same reason. Same device (iPad Air 5th generation) and same OS version (17.5.1), saying the app gets stuck on the splash screen. We've tested on as many real devices as we can find and cannot reproduce the issue.

Is there a chance that this test device is faulty? Did you manage to solve your issue?
