It seems to me that you have duplicated rows in CatalogContentProperty in that language. The combination of (ObjectId, ObjectTypeId, LanguageName and MetaFieldId) is supposed to be unique, but that was not constrained in Commerce 9.11. So for some reasons, such as a faulty import, it can end up problematic. Would suggest you to upgrade to at least Commerce 9.14, which fixed that specific issue (bug COM-1459)

Quan.. You sir, are the man. Thank you so much, this is exactly what the cause of this was. CatalogContentProperty had only 4 duplicate records, but the entire site was like hosed. Good job!
