Hey there, @dmlaplan.
Thanks for posting your concern here in the Community. I'm here to help fix the errors you're getting after performing the Rebuild Utility in QuickBooks Desktop (QBDT).
As of right now, we haven't received any cases similar to this issue. Let's isolate this by checking the QBWin.log. This will help find the cause of these errors in your company file. Additionally, it logs messages and errors created by Verify, Rebuild, and Condense Data utilities, in a specific file.
Here's how:
1. On your Home page, press F2 or Ctrl+1 to open the Product Information window.
2. Press F3 or Ctrl+2 to expand the Tech Help window, then choose the Open File tab.
3. Select QBWin.log, then Open File.
4. Find the line that contains the LVL_ERROR to find where this error came from.
As a reference, you can also check out this article for further guidance: Find QBWin.log or QuickBooks.log files.
That's it! Give this a try and let me know how it goes on the comment section. I'm always here should you need further assistance. Have a great rest of the week.
