Error message Blu ray playback

[Anami]

Hello,
I have a common problem: With my MacBook (macOS 10.13.6) I'm getting the famous error message about the aacs code. Following the instruction about the library a database files nothing is changing. What can I do or where do I find more instructions to watch Blu ray on my Mac with VLC?
Thanks,
A.
