I went back to the USB Drive and ran BIAB from there
It is v905

Open song the SGU song(75 bars) ( that I created)
Load Set of Recent Styles (that I have curated and saved)

pick a style
and it plays fine

pick another style
and it plays fine

pick another style Poof, Gone!

I have experimented with the sequence of the styles, it does not change the outcome. I conclude that it is not caused by a single style.
