TypeError: can't pickle _thread.RLock objects

This error occurs when attempting to pickle an object that contains a `_thread.RLock` object.
Pickle is a Python module that is used to serialize and deserialize Python objects. It allows you to convert a Python object into a stream of bytes that can be transmitted over a network or saved to a file.
However, there are certain objects that cannot be pickled, and `_thread.RLock` is one of them. This object is used for thread synchronization and cannot be serialized or deserialized.
To solve this error, you can try to remove the `_thread.RLock` object from the object you are trying to pickle. Alternatively, you can use a different synchronization object that can be pickled, such as a `threading.Lock` object.
