Dependency failed for device at boot

thought blkid showed /dev/sda2: UUID="477afc62-10fd-4399-8dfd-be348508e3df" for sda2

This is the UUID of the device itself. However, the device itself isn’t what you are mounting. What you are mounting is the device created after unlocking the encrypted volume.

I know you mentioned in other GRUB thread that my boot is a mess. Is there any need to clean up?

There are two strange things:

• You are using and mounting your EFI partition at /boot. That works but is very atypical. For grub, it makes more sense to mount the EFI partition at /boot/efi or /efi because grub doesn’t require the kernel and initrams to be in the EFI partition.
• You have files in the /boot on your / partition that you are mounting over with your EFI partition. Again, that isn’t a problem but it probably means something went wrong at some point in the past.

I couldn’t run btrfs-assistantwhen I chrooted to fix the GRUB issues. Is that a limitation or chroot won’t allow to run it ?

There is no reason to run btrfs-assistant from a chroot. If you want to use btrfs-assistant to restore, you can do that without a chroot. You just need to unlock your luks partition and mount some part of the btrfs partition.
