If you've already tried these steps, you may need to Run the Clean Install Tool or Create a new Windows Admin User. You can refer to this article and go directly to Solution 4 and 5: What to do if you can't open QuickBooks Desktop.
However, if the issue persists, I'd recommend reaching out to our Desktop Support again so they can isolate this problem using their screen-share tool.
Please let me know the call goes so I can make sure you're fully taken care of. I'll be here to help if you have other questions. Have a good one.
Hi there, Red,
Yes, you can go back to the 2019 version. On another note, once you convert a company file to a newer version of QuickBooks, you can no longer open it in any earlier version. Please use the back up copy you created from QuickBooks 2019.
Then, manually enter the transactions you recently created, or you can import them. Here's an article for a guide in importing transactions: Import and export data in QuickBooks Desktop
We recommend following the troubleshooting steps above to fix any unwanted behavior of the software.
We are here to help if you have any questions.
