yours is not the first report I have heard with this issue—and no clear reasoning...

Was this a complete erase and reinstall of the macOS before you brought back in your user backup...(?) it is unclear from your post.

Any change if you toggle the F1,F2 key function?

If you where to fall back, it requires erase, reformat, initialize the parent drive—of course this require a viable backup of your user data.

install the older full installer which you can get from the Terminal.app

sudo softwareupdate --fetch-full-installer --full-installer-version 12.5

I received a software update version 12.5.1 monterey installed it after sometime touchbar vanished then i tried to completely erase my mac using recovery option and fresh installed macOs Monterey but still touch bar not working

yes, unfortunate. I have no explanation as to why on a M1...

"after sometime" this makes it sound like no direct one to one correlation (?) with the update but a coincidence?

If it is hardware issue— you need to contact AppleCare Support at 1-800-APLCARE (800-275-2273)

If you are prepared to fall back (12.5)— you can try that , and see if it is resurrected from the dead.

you can always call Call Customer Support  (800) MY–APPLE (800–692–7753)
