The product you are trying to add is not avaiable

The situation:

When trying to create an order from within the admin, I can’t add any products, the following error message comes up ‘Product that you are trying to add is not available’. It doesn’t matter the product, all of them raises the same error. Weirdest thing is, the process goes NORMAL in the frontend, problem is only within the panel.

What I have already tried:

  • Checking the salable quantity and if Source and Stock are assigned;
  • Running the below command:

INSERT IGNORE INTO inventory_source_item (source_code, sku, quantity, status) SELECT 'default', sku, qty, stock_status FROM (cataloginventory_stock_statusASlg JOINcatalog_product_entityASprd ON ((lg.product_id=prd.entity_id)))

  • Put a fresh new Magento installation on the server;
  • Uninstalling all unused modules;

I’ve been searching through the internet but no lucky until now. Currently using Magento 2.3.3
