Viking Rise assets not loading

[JackHarris1973]

Hi, I've been having trouble getting assets from Viking Rise to load. I've checked the .bundle files using HxD, and the file heading is:

UnityFS�����5.x.x�2022.3.62f2

I've been using 2022.3.62f2 as the version number, but so far I just get "No Unity file can be loaded" errors. Here's the log:

Sample file here.

Well, as Studio says, blockInfo data is encrypted.
The first 40-42 bytes of blockInfo data(from 0x40) are encrypted/obfuscated.

Is there any way around that?

Who knows.
As always, try to find some info on the Internet.
If the game is popular, a decryption method may be described somewhere.
