I think whoever wrote the bio meant the September Songs film (1994) there—Lost in the Stars (1990) was also a Kurt Weill tribute project but Polly didn’t take part in it (Marianne Faithfull sang “Ballad of the Soldier’s Wife” on that one).
The biog desn't mention "September Songs: The Music of Kurt Weill" from 1994 (the full movie is here:
https://www.youtube.com/watch?v=5ygp9rK_p3E&t=1536s, PJ's performance is at 21:42, it's a fairly known PJ cover song, and i did watch the isolated clip more than once in the past) at all, so there's a good chance the writer did indeed mistake the "Lost in the Stars" tribute album for the movie PJ starred in, but this opens the question on where he/she found the 1990 date, since youtube, google and wikipedia state that the "Lost in the Stars" tribute album was released in 1985.
As for an actual "Lost in the Stars" 1990 movie, google only brings up a chinese 2022 movie, a soviet 1974 one and a 1960 french play; IMDb says nothing at all about it ( really weird, that's a site that has many unknown movies!), so it's either an hyper-obscure local film no one has ever heard about or , probably, it never existed.
