This is just issue6721 again. The workaround is easy: just add `multiprocessing.set_start_method("forkserver")` at the start of your program. Also, this is more or less documented, though quite tersely: """Note that safely forking a multithreaded process is problematic."" https://docs.python.org/3/library/multiprocessing.html#contexts-and-start-methods
