Encryption problem on Pinebook

Ok, so first, I had to:

Sudo su
export CRYPT="y"
bash manjaro-arm-installer

If I didn't use sudo su, the value of CRYPT set by the export command wasn't noticed by the installer if run as 'sudo manjaro-arm-installer'. So the current README failed me there.

I ran the installer from an SD card which has a clean PineBookPro Manjaro installation on it. I first installed all dependencies mentioned in the README and fully erased and unmounted the eMMC of the pinebook pro. Then I ran the above commands.

The GUI comes up, works fine, yet never asks for an encryption password. After the GUI closes it does indeed ask for an encryption password. Yet, when I enter it, it then throws an error stating the eMMC device of the PBP is 'not a valid LUKS device'.

After that the installation continues. But after reboot when trying to boot from the eMMC there is an error stating "Failed to open encryption mapping: the device (DeviceUUID) is not a LUKS volume and the crypto= parameter was not specified"

Then some messages about device not found and the PineBookPro drops into emergency shell..
