Why can't I open word or pdf files off my Asus ZenPad desktop?

[AC Question]

After I did an android security patch level upgrade on my Asus Zenpad 10 on June 1, 2017, I could no longer open word docs or pdf files that I had added to the desktop. Before the upgrade I could open them. I can open them from the files just not the desktop.

Welcome to Android Central! Did you already try removing the shortcuts for those files from the homescreen, then creating new shortcuts?
