It happened after ``` zypper dup && reboot
Multiboot with Debian 12.
/boot is on separate partition because Debian's grub can't access btrfs.
cat /etc/fstab

I've tried from TW grub command line:set root=(hd0,6) linux (hd0,7)/boot/vmlinuz-6.5.4-1-pae root=/dev/sda6 initrd (hd0,7)/boot/initrd-6.5.4-1-pae boot
but You are in emergency mode. After logging in, type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, or "exit" to continue bootup. Give root password for maintenance (or press Control-D to continue) Reloading system manager configuration. Starting default.target. You are in emergency mode. After logging in, type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, or "exit" to continue bootup. Give root password for maintenance (or press Control-D to continue)
journalctl -xb mount: /boot/grub2: unknown filesystem type 'ext4'. ... boot-grub2.mount: Failed with result 'exit-code'. Failed to mount /boot/grub2.
Any idea please ?
