In App Purchases button crashing for reviewer, but not for me

Hi, I am trying to add In App Purchases into my app. When I run my code in Xcode on a simulator and my own iPhone, it works perfectly fine. But when I submitted my app for App Review, they said that my app had crashed for them when they tried purchasing something. Why is this? Something that might be the problem is that the In App Purchase in the App Store Connect is still in review, but it's been in review for a very long time(~3-5 days) so I am just going to assume that it will be approved when my app is. Again, the app works completely fine on my device. Here are the three crash logs they gave to me(pastebin is down right now, so using an alternative):

  • https://pastes.io/g7pjx5fp0m
  • https://pastes.io/ftjpcoasam
  • https://pastes.io/5wh0ro6zl2

Here is my code: https://pastes.io/nivmrvwax9

Please help!

Open Xcode, open project, go to the organizer, select your app and try to download any crash reports that will automatically symbolicate with the source code.
