Raspi 2: Funimation plugin error

Hello everyone, I have a Raspi 2 with OSMC installed that I use as a media center. I have used the Funimation Kodi Plugin for quite a long time and then out of the blue I began getting errors whenever I tried to open it. The error told me to consult the log (Scroll to line 47262 for an example of the error):
I have tried reinstalling and rolling back the plugin many times and none of those operations fixed the problem at all. Any thoughts on what is gong on?
Thanks, The_Snowman
