This could happen because two mutually dependent network reactions were somehow scheduled with the same level. One reason why this would only manifest in the TS target would be because in the C target there are multiple cores, so reactions on the same level are less likely to block each other.
However, it looks like this is a deadlock during shutdown, so it could be a bug in the coordination of shutdown instead of a problem with level assignment. It is possible that the main reason to suspect the level assignment is merely that the purpose of the SpuriousDependency test is to check TPO.
A bug is suspected in the level assignment for federated execution. This is the level assignment which is based on TPO. See https://github.com/lf-lang/lingua-franca/actions/runs/9148420154/job/25150943808?pr=2262. This link will go stale, so here is the relevant part of the logs:
