Nothing is working to try to revive my Quickbooks 2020 for Mac Desktop.  All of the normally clickable buttons on the top header do not respond other than the colored spinning ball.  There is no way to access anything at all.  It is the same as a crashed site.  Over 10 years of my business are held hostage.  It has been suggested to install a QB 2021 or newer, but there is no way to do that.  No way to access my account number or access the migration assistant.  This is horrible.
