It's really hard to tell how often this is happening because it's getting grouped with other issues in Sentry. It seems like switching sync manager to uniffi might fix this error or at least make it easier to debug. Once we do that, I don't think there will be any ffi_support dependency.

We haven't seen this recently, sync manager has since moved to uniffi and parking_lot, so I think we can close it.
