Wishlist function does not work - Item (Magento\Wishlist\Model\Item) with the same ID "5192" already exists

Question

We are having an issues with wishlist function. Products are not added to the wishlist.

In system.log and exception.log we get the following messages, when a customer click on "add to wishlist" in frontend:

system.log

[2020-01-26 17:32:00] main.CRITICAL: Item (Magento\Wishlist\Model\Item) with the same ID "5192" already exists. [] []

Exception.log

[2020-01-26 17:20:08] main.CRITICAL: The product that was requested doesn't exist. Verify the product and try again. {"exception":"[object] (Magento\\Framework\\Exception\\NoSuchEntityException(code: 0): The product that was requested doesn't exist. Verify the product and try again. at /home/xxxxx/www/vendor/magento/module-catalog/Model/ProductRepository.php:310)"} []

customer/section/load/ message: "Item (Magento\Wishlist\Model\Item\Interceptor) with the same ID "13620" already exists."

Does any one know how can we fix this issue?

Best regards, Jesper
