And where’s the Traceback information for the exception ?

Following code work fine on my WIN10, and bz2 is a built-in library on my Python 3.11.2

import bz2

    with open(input_file, 'rb') as f_in:
        with open(output_file, 'wb') as f_out:

            for data in iter(lambda: f_in.read(4096), b''):
                decompressed_data = decompressor.decompress(data)
                f_out.write(decompressed_data)

In Changelog of python 3.12.0

bpo-23224: Fix segfaults when creating lzma.LZMADecompressor and bz2.BZ2Decompressor objects without calling init(), and fix leakage of locks and internal buffers when calling the init() methods of lzma.LZMADecompressor, lzma.LZMACompressor, bz2.BZ2Compressor, and bz2.BZ2Decompressor objects multiple times.

bpo-33916: bz2 and lzma: When Decompressor.init() is called twice, free the old lock to not leak memory.
