Upload Failed: "The app contains one or more corrupted binaries" - Xcode 26.3 / macOS Sequoia 15.8

I'm encountering a validation failure when uploading my app to App Store Connect. The upload itself completes successfully, but Apple's server-side validation fails with the following error:

"The app contains one or more corrupted binaries. Rebuild the app and resubmit. (ID: 087e356b-4dc3-4e52-8d61-ddee9e3c74e7)"

App Information

• App Name: 万华电商
• Bundle ID: com.imhehe.wanhuads
• Version: 1.0.25 (Build 2)
• Distribution: iOS App Store

Environment

• Xcode: 26.3
• macOS: Sequoia 15.8
• Team: Wanhua Petrochemical Co.,Ltd

Steps Already Taken

I have tried the following troubleshooting steps, but the issue persists:

1. Cleaned Derived Data and removed old Archives
2. Executed Product > Clean Build Folder
3. Re-archived the app with a fresh build
4. Re-uploaded via Xcode Organizer

The upload appears to succeed (ContentDelivery returns 201 Created), but the binary fails during Apple's server-side validation with the corrupted binaries error.

What I'm Looking For

Could someone help clarify what might cause this server-side validation failure, and what additional steps I should take to resolve it? I'm particularly interested in:

• Whether there are known issues with Xcode 26.3 and App Store validation
• Any specific binary integrity checks that might be failing on Apple's side
• Whether there are additional diagnostic steps I can take to identify which binary is flagged as corrupted

Attachments

I have attached the full upload log for reference. Please let me know if any additional information would be helpful.

Thank you in advance for any guidance.
