If it’s a movie blu ray you can usually play the “index.bdmv” file in a compatible media player e.g. VLC definitely works. MPC-HC / MPC-BE works too, I think(?) MPV can play them too. As well as Jellyfin and Kodi if that’s your thing.
Alternatively browse into the “STREAM” folder, usually the biggest .m2ts file in there is the actual movie or whatever it is you want to play. The above media players can play that directly if preferred.
For TV series the above usually works too but the episodes are usually split out among multiple .m2ts files so it might be easier just to play them directly in that case.
