The Nutrition game regularly gets stuck when sending the changes

What

The Nutrition game regularly gets stuck when sending the changes: the Send button has the spinner and the next product is never loaded.

Steps to reproduce the behavior:

1. Log in and open https://hunger.openfoodfacts.org/nutrition
2. Play the game until it gets stuck. It may take 10-20 products.
3. When the game gets stuck the JavaScript console shows the following errors which appear when sending the result:

Blocage d’une requête multiorigine (Cross-Origin Request) : la politique « Same Origin » ne permet pas de consulter la ressource distante située sur https://robotoff.openfoodfacts.org/api/v1/insights/annotate. Raison : échec de la requête CORS. Code d’état : (null).

Uncaught (in promise) TypeError: NetworkError when attempting to fetch resource.

    renderSubmitRow https://hunger.openfoodfacts.org/assets/index-BfEHioUo.js:1302
    handleEvent https://hunger.openfoodfacts.org/assets/index-BfEHioUo.js:366

The "cross-origin" issue makes it look like it may not just be a network error.

Expected behavior

• Load the next product to fix.

Workaround

• Reload the page. This normally gets the same product.
• Usually the data has been saved despite the issue which can be checked in game or by clicking "View Product".
• Clicking on Send again is likely to get stuck again. Instead click on Ignore since the data has been fixed already.

Platform (Desktop, Mobile, Hunger Games)

• OS: Firefox 141.0

I never have this issue when working on the categories or logos. It's only the nutrition game that gets stuck which is in part why I suspect this is in an issue with the game rather than a generic network / server issue.
