Welcome to the Community, @SantanasAC. I've got some information you need to fix these unrecoverable error you’ve encountered in QuickBooks Online.
When you try to open QuickBooks Desktop or work on it, an unrecoverable error occurs. To get rid of these issues and go back to work, let's attempt another troubleshooting steps. Ensure to create a backup of your company file before proceeding with the process.
To begin, determine how many users are impacted by using different login passwords to access the same company file. If the problem only affects one user, the person's logged-in credentials may be compromised. If so, recreate the damaged user.
Then, suppress your QBDT. Here’s how:
- Press and hold the Ctrl key.
- Double-click your QuickBooks program icon.
- Hold the Ctrl key until the No Company Open window shows.
- Choose the desired company file from the No Company Open window.
- Press and hold the Alt key, then select Open.
- If you are prompted for your log in information, release the Alt key, then enter your user name and password. Please know that if you are not prompted for your user name and password, do not release the Alt key.
- Press and hold the Alt key, then select OK. Do not release the Alt key until your file is completely open. Also, if 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.
