I appreciate the steps you've performed, CaymanBeach.

Let's try another troubleshooting step to get you back to work. Ensure to create a backup of your company file before proceeding with the process.

Try suppressing your QuickBooks Desktop. I'll walk you through how:

1. Press and hold the Ctrl key.
2. Double-click your QuickBooks program icon.
3. Hold the Ctrl key until the No Company Open window shows.
   
4. Select the desired company file from the No Company Open window.
5. Press and hold the Alt key, then select Open.
6. If you are prompted for your login information, release the Alt key, then enter your user name and password.
   Important: If you are not prompted for your user name and password, do not release the Alt key.
7. Press and hold the Alt key, then select OK. Do not release the Alt key until your file is completely open.
   Note: QuickBooks will display a blank screen. If you can highlight a QuickBooks menu by just hovering your pointer to it, your company file is completely open.

If the problem continues, please check the Unrecoverable Error: General Troubleshooting Steps for additional solutions to get this resolved. 

However, if the problem persists, I'd recommend reaching out to our Phone Support team. An agent will do a screen share with you to investigate this further. Here's how:
 

1. Click the Help menu, and then select QuickBooks Desktop Help.
2. Scroll down and click Contact Us.
3. Enter I can't find my bank on the list.
4. Select either Message an Agent or Get a callback from us.

Please keep me posted on how the steps work. I'll be right here if you have follow up questions.
