It looks like there was some unintentional breakage of `emscripten_sync_run_in_main_thread` in December. I left a comment on the relevant PR: https://github.com/emscripten-core/emscripten/pull/15756#issuecomment-1400603196 .
That being said, the best way to send work to other threads these days is using the proxy queue mechanism in proxying.h <https://emscripten.org/docs/api_reference/proxying.h.html>. These new APIs are safer to use to proxy nontrivial work, give you more control over when work is executed, and give you more control over how you wait for the work to be done. FWIW, the older `emscripetn_async_run_in_main_thread` and other proxying APIs in threading.h have been internally reimplemented in terms of proxying.h as well.
