[Error] Strange Error when encountering wild Pokemon

[Danyxx86]

I recently updated my game to include both the latest fixes and the Gen 8 Project

Everything runs fine until you encounter a wild Pokemon, in which case the game displays this error and crashes

[Pokémon Essentials version 19.1]
[Generation 8 Project v1.1.0]
[v19 Hotfixes 1.0.4]
[v19.1 Hotfixes 1.0.5]

Exception: NoMethodError
Message: undefined method `[]' for nil:NilClass

I am not an expert on coding, so I have no idea where to even start fixing this. If anyone could point me in the right direction, that would be really helpful. Willing to learn in the process of course, so next time I know what I'm looking at

Please make sure you don't skip any of the steps in "Installation and Update Instructions", especially step 7. You don't have to be an expert in coding to follow basic instructions.
