boot failed after upgrade 22.12.1 to 22.12.2 "You need to load the kernel first"

[demoli]

I use true nas scale since the beta version
I do all updates. No issues.
but this time...22.12.1 to 22.12.2 => no boot... "You need to load the kernel first"... for all grub entries, (at least 10 entries)
I did the update as usual from the GUI

My Nas
Motherboard : ASROCK J5040 https://www.asrock.com/MB/Intel/J5040-ITX/index.us.asp (Bios is up to date)
No change in bios setup since severals monhs
System installed on NVMe Corsair Force series MP510 https://www.corsair.com/fr/fr/Catég...SSD-M-2/Force-Series-MP510/p/CSSD-F240GBMP510
nvme is on glotrends Adaptator M.2 PCIe NVMe PA09-HS
4 SATA disks for storage

All disks seems OK (nvme and sata).

Maybye a problem with grub? why now when all other updates have worked?

is it possible to repair grub ?, For example with trunas scale installer ? or from a live linux with chroot.
Or is it possible to reinstall truenas while keeping the setup?

Grub is like this

Code:

linux /ROOT/22.12.2@/boot/vmlinuz-5.15.7+truenas root=ZFS=boot-pool/ROOT/22.12.2 ro console=tty1 console=ttys0,115200 libata.allow_tpm=1 amd8iommu=on iommu=pt kvm_amd.npt=1 kvm_amd.avic=1 intel_iommu=on zfsforce=1 nme_core.multipath=N
initrd /ROOT/22/22.12.2@/boot/initrd.img-5.15.79+truenas
