update

And when I quit QB desktop and restart, it presents login screen; I login and get this:

Oops! QuickBooks has encountered an error and needs to close. Any unsaved work will be lost.; 

Relaunch or Quit. Doesn't matter which I select, QB quits, then I restart to gray screen, no options - right back to where I started!!!

Hey there, RickL.

Thanks for reaching out to the Community about the issue you experienced after updating QuickBooks. I’m here to share some details about the error.

Our engineers are aware of this issue, and they're currently investigating this particular occurrence (INV-17577). They’re working towards finding a permanent solution.

While waiting for the fix, I recommend reaching out to our Online Support Team. They can add you to our list of affected users, and you'll receive an email notification once an update is available.

As a workaround, access your QBO company via a supported web browser. If you receive the same error message, then refresh the application.

Here’s how:

1. Click Help.
2. Choose Reset App Data.
3. Then, close and reopen the app.

I appreciate your patience while we're working on this. Reach out to me directly if you have other concerns. I'm always around to help.

Thank you for your update. I waited a day and went back in to find another update - ran it and got back to a functioning QB. HOWEVER, I've not been able to update / sync my bank accounts since this happened. Is this another known problem? How do I notify QB support as you suggested?

Hello, @RickL.

Thanks for sharing the steps you’ve performed in order to resolve the issue.

Since, now that the Bank Feeds is not working after the recent update, you may need to contact our Technical Support Team for further assistance.

3.    Download a statement to your computer.
4.    In QuickBooks, open the Downloaded Transactions window and select the Import File icon to import your statement.
