Unhappy No module named 'calibre_plugins'

I have almost completed my plugin. But when I click the icon in the menu bar, it complains:

```
Traceback (most recent call last):
File "/usr/bin/calibre-parallel", line 21, in <module>
sys.exit(main())
^^^^^^
File "/usr/lib/calibre/calibre/utils/ipc/worker.py", line 205, in main
name, args, kwargs, desc = eintr_retry_call(conn.recv)
^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/lib/calibre/calibre/utils/ipc/__init__.py", line 24, in eintr_retry_call
return func(*args, **kwargs)
^^^^^^^^^^^^^^^^^^^^^
File "/usr/lib/python3.11/multiprocessing/connection.py", line 250, in recv
return _ForkingPickler.loads(buf.getbuffer())
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ModuleNotFoundError: No module named 'calibre_plugins'
```

Could you help me please? Here is the source code: https://github.com/otakutyrant/new_words

I have removed the job manager so that my plugin can work. Now the old code with the broken job manger is in https://github.com/otakutyrant/new_w...ee/job_manager

Dont serialize objects from your plugin. Use basic python types only. That means when calling functions in a job, those functions should take only basic types as parameters.

Thank you! I'll try to fix that.

I tried the pickle library and found out it can pickle namedtuple objects. However I have to convert the namedtuple objects to tuple objects in my plugin to make them work with the job manager. It is a mystery to me why Calibre cannot serialize them and throw `ModuleNotFoundError`.
