Just to confirm, this is still an issue. Can I confirm if the accessor method is being added into the interface?

still issue, please

freshly duplicated on 2.4.6-p5 - product pushed to queue initially and failed to hydrated back is obtained by productRepository in adminhtml area

update:
as a quick workaround, resetting the related extension attribute (since related interfaces/classes are marked as deprecated, really no see any chance of getting any official solution)

$product->getExtensionAttributes()->setData('stock_item', null);
