I reinstalled Windows 10 but not in a compatibility mode. Instead of installing the Windows Updates first, I installed the Quickbooks Desktop Pro 2020. It opened. I started installing all of my other software programs and between each install I checked to see if Quickbooks would open. It did - even after I installed the Windows Updates. I'm a little baffled as to why it's working now. I'm thinking it might have something to do with a conflict with another software - like the anti-virus that was pre-installed when I purchased the laptop. So although I found a solution - I'm still not sure what was causing the issue in the first place.
