Restoring a backup from both the OneDrive and local drive is a good place to start, IH8QuikB. This helps us isolate the behavior to know where the issue is coming from.

Since the backup won't restore after trying out both ways, then the backup file is probably damaged or corrupted. With that being said, it would be best to contact our Technical Support Team. We'll help you fix the file so you can restore the backup successfully.

Here's how to get our contact number:

1. Go to this link https://help.quickbooks.intuit.com/en_US/contact.
2. Select QuickBooks Desktop, and then choose your version.
3. Click the Solving Issues & Error Messages topic.
4. Select the File & Network Management sub topic.
5. Scroll down and click the Get Phone Number button.

Don't hesitate to let me know if you need anything else.
