Need help with extracting files from encrypted unity asset bundles [Beat Refle]

[ridrkseven]

Hi, first time posting. There's this game that came out recently, and I want to extract the raw files from it, namely the animation assets and the music files, the former for *research purposes*. Tried using UABE, uTiny, and AssetStudio, all don't work.

Game is Beat Refle, available on steam.

Here's the sample files (the SE asset bundle, and the assembly files if needed.):

Please let me know if there's more needed to get extraction working.
