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?
