StoreKit testing not working on iOS26.5 simulator

Hi,

I'm trying to run our StoreKit unit tests with Xcode26.5 on an iOS26.5 simulator. Host computer has macOS26.5.

All tests are failing and in the console I see logs such as

[SKTestSession] Error saving configuration file: Error Domain=SKInternalErrorDomain Code=3 "(null)"
[SKTestSession] Error deleting all transactions: Error Domain=SKInternalErrorDomain Code=3 "(null)"
[SKTestSession] Error clearing overrides: Error Domain=SKInternalErrorDomain Code=3 "(null)"
[SKTestSession] Error setting value to 1 for identifier 2 for jp.unext.mediaplayer: Error Domain=SKInternalErrorDomain Code=3 "(null)"

And the simulator asks me to provide my AppleID.

Tests have been broken since at least 26.4

The release notes claims that it has been fixed but not for me. https://developer.apple.com/documentation/ios-ipados-release-notes/ios-ipados-26_5-release-notes#StoreKit-Testing-in-Xcode

Does anyone else have the same issue?

Reported FB22774836 just in case.
