[Error] Essentials Error v20.1

[SaucySpirit]

Hello, I've been getting this error when launching my game ever since I changed some of the scripts for EBDX. I made an edit so the game would prioritize animated sprites over still sprites. I used the code from this post and it started giving me the error (https://www.pokecommunity.com/threads/animated-sprites-ebdx-problem-19-1.453527/).

Because it started giving me the error, I undid the changes and it still gave me the error. I tried replacing the script file entirely with an unedited version and it still gave me the error. The error is listed below.

[Pokémon Essentials version 20.1]
[v20.1 Hotfixes 1.0.7]
