Hello Choicie,
Welcome to the Community page,
Can you go to this link https://downloads.quickbooks.com/app/qbdt/products after clicking the country, product and version (UK, Pro/Premier,2019) you should get a page that says downloads & updates, and below here's your product. Then you need to download the patch manually, close QuickBooks and then run the patch to update 2019 to release 10 and that should work and resolve your issue for you.
