Thank you for submitting your first issue here. Please be sure you have uploaded your AssetRipper.log file. It is in the same folder as the exe file. :)

I suspect this is an upstream issue with the library I use.

You can grab the files out of the apk from a site like this: https://apkpure.com/whiteout-survival/com.gof.global Let me know if uploading one of the unity3d files helps debug.

FWIW, I'm getting similar errors for this game with other tools I've used in the past like AssetStudio and UABE.

Actually, your game is just encrypted.
