You could give the unofficial TWRP builds that I have in this post here:
These are built from what were the latest sources at the time, and may help with decryption. Only thing is they are too big to flash, so you can only use "fastboot boot ..." to use them.
Now, it's pretty clear to me what happened. Restoring data from release nine is the root cause of your trouble. PD (AOSP based) release nine is a totally different ROM. This one here has been started from scratch and based off of CAF.
In other words: Coming from PD AOSP requires a clean flash.
