Lately my Anki deck throws up an error whenever I open it.

プラグインにエラーが発生しました。プラグインの製作者までお知らせ下さい。

K so does anyone know what that means?? I located a working version of the deck that doesn't throw up that error from the backups but it's missing 150+ cards. I thought I could just manually update that deck to where my current deck is at and hope it doesn't break again.

I'm just confused as to why or how something like this happens and what can be done to fix it. All other decks are fine and plugins all work correctly for other decks, so I've isolated the deck as the problem. Just confuses me (and slightly annoys me to say the least).

There are more appropriate places to be asking this question.
