So I created a buildroot package for pycryptodome based off the LibreElec package. Cross compiling this with python for ARM was all sorts of fun. I had to also create a new package for distutilscross in order for it to compile, and even then there was a single file that is apparently not compatible with ARM (_raw_aesni.so), so I have to remove that right after compile in order for it to complete.
Anyways, package installed and I have confirmed it's installed to /usr/lib/python2.7/site-packages/Crypto. Now KODI crashes as soon as the netflix addon is installed and will not restart (crashes immediately).
I've confirmed all of the dependencies for this addon install successfully, and when I remove the addons/plugin.video.netflix folder then I can start KODI back up with all the other dependencies still there.
I have also tested the last few versions of the plugin and they all have the same issue. Here is a log with all the debug enabled from when I start kodi and install the netflix plugin with all the dependencies already there.

Just confirmed that the exact same issue occurs when the YouTube app is installed, by the way.
Really appreciating the speedy replies. Let me know what to try next please
