Hey Everyone I think I may have semi-solved the problem.

I went with my original laid-out plan and bought a cheap $3 ebook from Kobo that was the same as the problem ebook in terms of DRM protection, EPUB 3 with Adobe DRM enabled. I also bought a $1 EPUB 3 DRM-free ebook to further solidify JSWolf's test results from earlier involving EPUB 3 without DRM. The DRM-free EPUB 3 ebook was already unlocked when I downloaded it so I was able to read it fine with no issues.

I unlocked the DRM protected EPUB 3 ebook with my Pocketbook. I opened it and I was expecting a crash but instead the thing opened fine and I was able to navigate the pages with no issues and no system crash.

I believe the problem probably originates with the mentioned book that I first encountered this issue and the DRM file that goes with it not EPUB 3 DRM-protected books in general. I'll message Kobo about the issue but I don't know if they'll even care to fix it until more people start complaining which may never happen.

In the meantime I'll probably switch to another ebook site to buy EPUB 3 DRM protected books from rather then going through a possible crap shoot with Kobo going forward.

Thank you everyone for sticking to it with me as we narrowed down solutions it was very helpful. I've never received this level of help on any forum I have ever been a member of in my life.

Thank you again.
