Oh wow that's weird, I'm so sorry about that!
Can you please let me know where in the game this happened and what actions you did so I can check it out? Thanks for letting me know! :)
That's interesting... I downloaded, extracted, and tested the game out again myself and I didn't run into this issue.
Maybe it's a glitch with how it extracted or downloaded onto your computer since that type of error only comes up when there's a missing file. Can you try downloading the game again?
This is so weird, I'm sorry!
