did previous versions work fine? please open upstream issue about it, not much I can do. if they have a patch I can probably add it. But I really suggest not to rely on parallel-compiler, it's experimental and masked for a reason =)
I had initially created an upstream bug ht tps://github.com/rust-lang/rust/issues/89108#issuecomment-922537950
