In-App Purchase Sandbox completely broken on macOS Catalina

Question

I have a sandbox test user which I used to test In-App purchases. Everything was working until I upgraded to macOS Catalina (10.15.3). If I try to refresh a receipt when it's not available with SKReceiptRefreshRequest() it fails with error: Error Domain=SKErrorDomain Code=0 "(null)".

Calling exit(173) shows error message: {application name} is damaged and can't be opened. Delete {application name} and download it again from the App Store.

In any case I can see a warning in Console.app: Subsystem: com.apple.commerce Category: CommerceKit message: : Error fetching receipt for {application name} - Error Domain=com.apple.commerce.server Code=500317 "(null)".

There was no problem on Mojave so it was broken in Catalina. Did anyone found a solution?

Have you tried logging out of the App Store as mentioned in this similar question: https://stackoverflow.com/a/56349529/43615 — Thomas Tempelmann, Mar 27 '20 at 18:25
