Unfortunately cannot share however these are generated files and until the upgrade no issues. Currently trying to rollback to the highest version without the issue.
Are we able to log more detail that will share insight for you that wouldn't involve sharing file contents?

No. It's not possible for us to troubleshoot these kind of problem through logging. The fact that the code is failing is due to it is seeing something unexpected. It could be valid PDF construct that our code did not handle properly, or invalid PDF construct that our code could not gracefully handle. In either case the next logical step is we need to see exactly what that unexpected is. Once we know exactly what that unexpected is, we will change our code to cope with it accordingly. In order to do this we must have the PDF files in question.
Obviously we are not interested in the content of your file. We are simply interested in finding out why our code is failing with your PDF file. We will have no problem to sign NDA with you if needed.

Btw I sent test data but I've confirmed this appears in 23.1.45 as a bug but not versions before.

Thanks I tested it and it doesn't fail on the merge, but I now have a new error same document you have you can reproduce:
using (HtmlToPdfSession session = HtmlToPdfSession.Create())
{
session.LoadHtml(CreateHtmlStyleSheet(stylesheetpath) + htmlContent);
Paginator paginator = session.CreatePaginator();
EO.Pdf.HtmlToPdfException: 'Conversion failed.'
The Paginator paginator = session.CreatePaginator(); does this:
NullReferenceException: Object reference not set to an instance of an object.
This exception was originally thrown at this call stack:
[External Code]
This never failed before.
