IDA 7.x crashes when using Diaphora

Problem description

While Diaphora supports some old versions of IDA, these versions are old and not 100% compatible with some modern Python versions. If you are experiencing weird problems with, for example, IDA 7.4 or 7.5, please be sure to use Python 3.8.5 to avoid rare problems.
