Hey there, @paulsiam. We appreciate you for sharing the screenshot of the file and letting us know that you encountered no errors while backing up the company file. Your cooperation is greatly appreciated. Allow us to further help you this time.

Upon reviewing the screenshot you sent, it has the .tmp on its file name. Which means temporarily backed up. To fix this, let's perform first the Verify Rebuild data and utilities. Doing so will help us identify the typical errors in your company file and look for a fix. We can use the steps below for reference.

Verify your company data:

1. Go to Window, then select Close All.
2. From the File, choose Utilities.
3. Pick Verify Data. If you see:
   - QuickBooks detected no problems with your data—your data is clean, and you don’t need to do anything else.
   - An error message—search for it on our QuickBooks Desktop support site for how to fix it.
   - Your data has lost integrity—Data damage was found in the file. Rebuild your data to fix it.

After that, rebuild your company file data. Follow the steps below:

1. Go to File, Utilities, and then select Rebuild Data.
2. QuickBooks will ask you to make a backup before it rebuilds your company file. Choose OK. A backup is required before you can rebuild.
3. Look where you want to save your backup, then OK. Never replace another backup file. Type in a new name in the File name and click Save.
4. Tap OK when you get the message Rebuild has completed.
5. Go to File again, choose Utilities, then select Verify Data again to check for additional damage.
   a. If the verification finds more damage, fix it manually.
   b. If an error can't be found, you can restore a recent backup. Go to File, then select Open or Restore Company. Never replace your existing company file, we need to enter the info into your company file again since the backup was created.

If you experience the same issue, we can attempt to resolve it by updating your QBDT to the latest version and then recreating a backup of your company file. 

Moreover, if the issue has never been fixed, I recommend contacting QBDT contact support to help you review the account and look for the root cause of it.
