Hello,
we observed the following problem when trying to read any *.pptx-file via
new Presentation(fileData) and having the corrupted font (we attached it) inside the windows Font-folder.
In Version 15.5.1 the following Exception occurs:
java.lang.NullPointerException

(Looks like Issue SLIDESJAVA-35093)
This only happens when you have a broken font inside the windows Font-Folder.
For our company this means the whole PowerPoint functionality is broken because of an global update for all clients that brought in a single faulty font.
Is there a workaround for it or can you fix the behaviour of parsing ALL Fonts before even loading a single Presentation.
Another Error occurs when placing a faulty Font inside the Windows-Font-folder and calling:
Slide.getThumbnail(float, float)
Then the Aspose hangs inside the following thread-stack:

This looks like the Problem desribed in:
https://forum.aspose.com/t/fontloader-hangs-in-15-8-0/140935
Because of the urgency of our problem and the impact for our application, wen need a workaround or fix for this.
Any help would be apriciated.
Thanks in advance
