pyhton: uncompyle6. AttributeError: module 'xdis.opcodes.opcode_39' has no attribute 'END_FINALLY'

При попытке декомпилировать file.pyc файл через uncompyle6 получаю это:

Попробовал установить xdis через pip install xdis, но результат не изменился

На выходе каждый раз получается почти пустой файл:
