No Unity file can be loaded

[JackHarris1973]

I'm trying to load .bundle files from the game Viking Rise. I've verified they're Unity files, using version 2022.3.61f1, but AssetStudio won't open them.

In most cases, this simply means that the files were somehow encrypted.
For this game you can use LukeFZ's Studio and work with the assets there, or just extract the files (File->Extract file/folder), after which you will be able to open the extracted files in AssetStudioMod.
