I see only this is legacy system or CSM install ?  
First thing to try is to boot into rescue ISO (installer) and arch-chroot as shown on the bottom of the wiki for BTRFS and encryption… (have in mind that you do **not** have the esp fat32 partition)

When inside the chroot:

1. update installed system `pacman -Syu`
2. regenerate kernel images according to your install latest ISO used dracut molder install or changed Mkinitcpio: `mkinitcpio -P`  
[Dracut](https://discovery.endeavouros.com/installation/dracut/2022/12/): `dracut-rebuild`
3. reinstall grub files: `grub-install /dev/sda` and regen grub.cfg: `grub-mkconfig -o /boot/grub/grub.cfg`  
logout the chroot and reboot into installed system (if lucky)
