I accidentally updated grub and broke my system entirely. On an encrypted device (I am able to chroot and access everything though). After a while with no luck I decided to purge grub and install rEFInd. I think I have everything correct, I'm pulling my hair out at this point and have no idea what I'm doing wrong.
I want to boot directly to the EFI stub and have /boot as my EFI partition with kernels and stubs. I'm going to show what I have now, I don't even care about the fact I'm showing IDs or anything. Let me know if there's something I'm missing out on or configuring incorrectly, or if there is any way to run more diagnostics.

Entire blkid command:

Do I need to provide a decryption key file? Am I supposed to be using the Partition UUID instead of the UUID somewhere?
