When you say never opens, do you mean the password is incorrect or you didn't get a prompt at all? If you haven't already, you can update your QuickBooks 2020 and open the company file again. However, if it's the same thing, please contact our QB Mac Support so they can check this further using more tools.

I'm just a comment away should you need more help with updating your QB or reaching out to Support.
