Audacity also has a free stem splitter (for windows). Need to download OpenVino AI plugin and then enable it in Audacity.
I don't know how well it works I have only tested it with some sample files. Option to select 2 stems (vocal, rest) or 4 stems (vocal, bass, drums, rest).

It is easy to check out since it is free.
