Check my reasoning on error: "not supported by this image"

I am getting this error when attempting to flash an image which I am sure is correct.
Luci also fails but does attempt, router resets with orange light then does not install new firmware.
I am also switching to stable release from a snap.

Am I correct in thinking that I am jumping too many upgrades since my current is:
22.03-snap... with 5.10.113 kernel?

Router is belkin rt322 / linksys e8450 (ubi)

Many thanks!

And you're upgrading to 23.05.4, correct?

Have you tested/tried sysupgrading to 22.03.x?

Yes upgrading to latest stable.

No I haven't, wanted to make sure I don't increase risk of bricking - I'll try that now.

Interesting update, I disconnected power over night, and this morning I am running the latest stable release! albiet I lost all my data.
Only thing I can think of is, RAM was emptied? /tmp folder cleared?

Ahhh, although I am having weird issues such as a reboot failed to turn back on...

Save config backup.
sysupgrading around 23.05.x or 22.03.x is unlikey to brick
