Background Upload Extension Bug on iOS 26.2

While implementing the new background backup feature introduced in iOS 26.1, I create a PHAssetResourceUploadJob in an Extension. On iOS 26.1, the system successfully triggers the upload. However, on iOS 26.2, although the job is created successfully and all related configurations are correctly set, the system does not trigger the upload.

Could you please help confirm the cause of this issue? Thank you.

I am also using an iOS 26.2 system real iPhone 12. However, when executing the "setUploadJobExtensionEnabled(true)" command, an error occurred: NSError    domain: PHPhotosErrorDomain    code: -1    localizedDescription: The operation couldn’t be completed. (PHPhotosErrorDomain error -1.) userInfo: [] The code for creating background tasks cannot be executed at all. Could you please tell me if there are any configuration issues that need to be addressed?
