Looking at the stack, it appears the dispatch causing issues is https://searchfox.org/mozilla-central/rev/4d6a262deed98ddb4d609de94048e7f97b6e85d3/ipc/glue/IdleSchedulerParent.cpp#80, which is trying to dispatch a runnable to a background thread.
Interestingly, the code is doing a check of !AppShutdown::IsInOrBeyond(ShutdownPhase::XPCOMShutdownThreads) already in order to avoid this check (https://searchfox.org/mozilla-central/rev/4d6a262deed98ddb4d609de94048e7f97b6e85d3/ipc/glue/IdleSchedulerParent.cpp#66-67), so it's surprising to me that we're able to hit this error.
The error should theoretically only happen after https://searchfox.org/mozilla-central/rev/4d6a262deed98ddb4d609de94048e7f97b6e85d3/xpcom/build/XPCOMInit.cpp#595 has been called, which happens after the XPCOMShutdownThreads shutdown phase, so we shouldn't enter this code anymore.
:jstutte - do you have any ideas how we could be entering this state?

There is always a (small) window for a race here between the check and the dispatch, other ways how we can end up like this I cannot really see. We would need kind of an atomic DispatchIfNotBeyond function to close this window, not sure if it is worth having, though.
Maybe the IdleScheduler could just stop working from an earlier phase?

May be made easier to avoid with bug 1824189, as we could use a fallible dispatch.
