So...I'm going to mark as resolved at this stage.
Maybe the original file I created was corrupted?

I eventually opened the file in question in BIAB 2022 for Windows and edited the lyrics.

It seems to have accepted the "new" windows saved file OK. (Maybe that cleared any corruption issues?

I've played the song through now on several occasions & it seems OK

I'll create another similar new song this week in BIAB 2024 MAC and see what happens next.
