No reader engine for this file or invalid file using most recent version #76
Description
Hello, I reinstalled this plugin today and am coming across issues that seem to have been addressed before. This happened in both the master and nightly branch.
After unzipping the package into the koreader plugin folder, I created a profile in the profiles folder using notepad (file name is jp.lua). I used the template to match my current anki note type and deck.
After ejecting my kobo (Kobo Libra H2O), I tried to open a document but came across the "No reader engine for this file or invalid file" error. It looks like others had this error before, and it was previously fixed. I just reinstalled today, so I should be using the most recent version to my knowledge (pulled directly as a zip from Github.)
When I go into the anki note settings and try to adjust the previous or following sentence amount, koreader crashes. I wonder if this is related to the other error?
Edit: When disabling the add-on, the "No reader engine for this file or invalid file" does not occur.
This is the crash log:

It's a scroll... It's a codex... It's KOReader!
