GRUB can't boot into encrypted partition

Hi, I recently upgraded my system and have had some issues since. Now, I can't boot into the system anymore since grub seems to have some issues with my encrypted partition. Attached, you can see the error message and my /etc/default/grub file. Notice that the UUID in the error message doesn't match the one specified in the file. Instead, it's the UUID of the decrypted partition. However, I always run mkinitcpio -P and grub-mkconfig -o /boot/grub/grub.cfg after modifying the file.

/etc/default/grub: https://media.discordapp.net/attachment … 205429.jpg

Re: GRUB can't boot into encrypted partition

You unlock the LUKS partition as "system" but try to mount / from "new_root".
Do you use LVM on LUKS?
If so, what's your LVM layout?
Also please show your /etc/mkinitcoip.conf.

I've changed it to this: and it still isn't working.
As to whether or not I'm using LVM i'm honestly not sure.
Here's the requested file:

Re: GRUB can't boot into encrypted partition

The decrypted device will be created under /dev/mapper.
i.e. cryptdevide=UUID=<UUID>:my_root will be created as /dev/mapper/my_root.
And don't use /dev/sdX? paths to specify devices as they are nondeterministic.
