Comment:

 The name `run_sync_in_worker_thread` was deprecated in py-anyio 3.0.0; the
 new name `anyio.to_thread.run_sync` should now be used. Last month py-
 anyio was updated from version 3.7.1 to 4.2.0. Although the py-anyio
 changelog does not mention it by name, I presume that
 `run_sync_in_worker_thread` was removed entirely in py-anyio 4.0.0 since
 there are half a dozen bullet points describing backwards-incompatible
 changes in that version.
