Auto-renewable subscription fails to submit — generic "errors with one or more of your items" / "unexpected error," but no field-level error shown

I'm trying to submit my app version together with two auto-renewable subscriptions (both in the same subscription group), and one of the two subscriptions will not submit, while the other submits with no issue.

Setup

One subscription group ("Crucibull Pro") with two subscriptions: Annual — $49.99/year — submits fine Weekly — $1.99/week — fails to submit Both are being submitted together with a new app build in a single review submission. The errors I get (they vary, none are field-specific)

"There are errors with one or more of your items. To fix them, you need to remove the items and add them again to your submission." "Sorry, something went wrong. Try your request again." "An unexpected error was encountered when submitting for review. If the issue persists please contact us." Critically, there is no red/field-level error anywhere on the Weekly subscription's page — its status is "Prepare for Submission" and every field is filled.

What I've tried (nothing has worked)

Verified every field on Weekly: reference name, product ID, 1-week duration, availability (all countries), price ($1.99 with a valid start date), localization (display name + description), tax category, and an App Review screenshot. Compared Weekly side-by-side with Annual (which submits fine) and matched every field. Changed Weekly's Tax Category to "Match to parent app" to match Annual. Removed and re-added the items to the submission (per the error message's advice) multiple times. Configured the subscription group ranking/levels. Deleted the original Weekly subscription and recreated it from scratch with a new Product ID — same result. Confirmed App Store Connect is stable (System Status all green) and still errors. Tried fresh submissions, different browser/incognito, and re-uploading the screenshot. Current state The Annual sub and the app build are ready and submit fine. The Weekly sub is fully configured, identical to Annual, freshly recreated, on a stable platform — and still throws generic submission errors with no indication of what's actually wrong.

Question Has anyone seen an auto-renewable subscription that's fully configured (and identical to a working one in the same group) fail to submit with only generic errors and no field-level detail? Is there a known backend/propagation issue, or a hidden requirement I'm missing? Any way to see the actual validation failure?

Thanks in advance.
