MikroTik SXTsq Lite2 (RBSXTsq2nD) - Initramfs 22.03.2 didn't boot, 21.02.x booted

I've been using OpenWrt for a few months.
My device is a MikroTik SXTsq Lite2 (RBSXTsq2nD).
The version used when first installed was version 21.02.x for MikroTik RouterBOARD LHG 2nD (LHG 2).
Then I did Sysupgrade to version 22.03.x after release.

A few days ago there was a power outage in my neighborhood and caused my device to not work or could not be remoted after the power returned to normal.

So I reverted to Mikrotik RouterOS using netinstall and then reinstalled OpenWRT.

But this time using:
https://downloads.openwrt.org/releases/22.03.2/targets/ath79/mikrotik/openwrt-22.03.2-ath79-mikrotik-mikrotik_routerboard-lhg-2nd-initramfs-kernel.bin

Unfortunately it always fails.

I can only install OpenWrt using version 21.02.x.
Is it normal?

shouldn't be, but without serial console, it's probably hard to diagnose why it isn't working ...

I have tried to install 22.03.2 using linux & windows.
Only 21.02.x was successful.
I don't know what the problem is.

Now I hesitate to do sysupgrade to 22.03.2.

You already proved you can recover it, go for the upgrade.

But the point is why can't I boot initramfs 22.03.2 while initramfs 21.02.x can?
What is the problem?

You tells us, you're the guy with the device...

Upgrading doesn't require the initramfs.

yeah i know...

but I'm talking about the first installation.

there it says "useful for first installation".
but in reality no, I have to use version 21.02.x for first install then do sysupgrade.

is there something wrong with initramfs 22.03.2 for my device?
