I have the same Issue:

Info:
I downloaded your free version to see how it would work before joining the club.
I tried looking for this issues under help center articles but could not fine any information.
When I go to create a invoice it goes to a blank white screen. If I click on the order and then the invoice it open the pdf viewer but there is no information in the viewer BLANK.
If I look in the folder wp-contents/upload/ywpi-pdf-invoice/2019 there are no files in this folder.
If I go to woocommerce orders none of the pdf plugin icons are in the right hand column
If I click on the order then I can see the PDF Icons.
After creating a invoice it does show up in woocommerce / orders under the order , but when I click to open it is blank.

I have done the debug like you stated in a another post a few days.
