Help using AssetStudio to export Sprites (Bandle Tale)

[xlasn]

I'm trying to use AssetStudio to export sprites as PNGs but I'm running into an issue that reads:

Index was outside the bounds of the array

Some Texture2D files export fine, but none of the Sprites do. I'll attach two of the .bundle files inside the StreamingAssets folder. They both open with AssetStudio, but inspecting/exporting any Sprite file throws an error. Does anyone know what I could do to solve this issue?
