I am playing all my Blu Ray discs using VLC, and I've been doing so since about 2015. VLC is free, so that's why I use it. But it needs a a bit of "help". I suggest that you register at a different website's forum keeping your username, do some reading, and repost your question. I'll look for it. Discussing this on VLC's forum could get both you and I permanently banned from posting because of forum rules.

Post in the OS-Specific forums. Obviously, the MacOS one.
Playing a Blu Ray disc using VLC in MacOS Ventura is more difficult than it ever was before. But I have a fully working setup now.
