Can't edit In-App-Purchase (Internal Server Error)

For three days in a row I can't edit one of my In App Purchases. I updated the promo picture before. Inside the App Store Connect table of purchases it appears "Rejected", but it says "Approved". On the App Store I can see the new picture, but inside App Store Connect I can't edit the purchase, because I get a page with empty fields and Internal Server Error.

Apple Support hasn't replied for days now ...

The problem is, that also my app is in review for two days now ... nothing happens. Can anyone help?
