I have also ran into a lot of Object reference not set to an instance of an object errors with the stack trace being somewhere deep inside ASPOSE. I have no problem with the errors but I would rather have some better explanation of what is going on.

Here is an example of one such stacktrace that I am currently looking at:

Hi Paul,

Thanks for your inquiry. Regarding the usage of the ‘interim build’ of Aspose.Words i.e. 11.6.1, it was only meant for a particular few customers who required it. We strongly recommend you please use the latest official release of Aspose.Words that is 11.9.0. I hope, this will help. Moreover, you can download the latest version of Aspose.Words from the following link:

Best regards,
