"""Searches for a JSON object within the string and returns the loaded JSON if found, otherwise returns None.

The function uses a greedy regular expression to match the first occurrence of a JSON object (enclosed in curly braces) within the input string. If a match is found, it attempts to parse the matched substring as JSON. If the parsing is successful, the parsed JSON object is returned; otherwise, None is returned.

Args:
    s (str): The input string to search for a JSON object.

Returns:
    Optional[Any]: The parsed JSON object if a valid JSON is found and successfully parsed, otherwise None.
