Thanks for the update, [MENTION=4544860]osm0sis[/MENTION]!

Unfortunately it seems the Magisk install isn't working, as the /magisk/aik-mobile folder isn't getting created. See log excerpt below:

Done!

Run 'aik' from the commandline when booted
then 'unpackimg.sh -.img' to get started
I:Updater process ended with RC=0
I:Legacy property environment disabled.
I:Install took 1 second(s).
Updating partition details...

Even when I manually created the folder, the aik helper script didn't get copied.
