See my discussion above that will fix your problem. IE doesn't need to be reinstalled (I couldn't get mine reinstalled) to use the fix above. I can't install IE on either my Win10 or Win11 computers. But with the fix, I can run QuickBooks 2020 Desktop Premier on either computer.
Don't bother with QB support responses. They don't work and QB wants you to "upgrade" to the cloud (leased) version. They are using this "issue" as a way to get us frustrated QB Desktop users to come over to the "cloudy side". (I've used QB for my IT business since 1995)
