We have the same problem with QuickBooks Pro 2021. I called into Support and the guy barely able to speak English tried for about an hour to figure it out then hung up when he couldn't find anything, I found a hack that works nicely but its ridiculous we have to resort to it. If you set the  QB downloads folder in Programdata to read-only it cant download the updates and doesn't know about them. then switch it back when you want to do updates.  I am recommending my clients move to a different product.
