Project publishing error

Good day to all members of this community,

I would like to ask you for help in connection with the project publishing to LMS/review. This project is formed by multiple scenes of different topics and videos. During the publishing process, I am getting an error:

<?xml version="1.0" encoding="utf-16"?>
<ErrorReport xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <UserId>aid|028ab842-2861-4b79-9061-a453ec0d9faa</UserId>
  <HardwareId>FV409-RPWWV-SNQ3F-VPUAU-U9VT1</HardwareId>
  <Message>Exception of type 'System.Exception' was thrown.</Message>
</ErrorReport>

If I publish each scene separately, there is no problem or error. This error occur only when publishing whole project. Thank you for your help.
