IAPs fail to load despite being approved

Hello, I got my app approved with some IAPS, then I got approved new IAPs (the ones I'll be using) and despite being approved, and my new build being approved in TestFlight beta testing, I can't get my IAPs to load (IAPs are not found and the purchase popup doesn't appear).

Here is a screenshot of the error result :

I really need your help, idk what to do. Thanks!!
