Windows gone from dual boot (GRUB)

Hello,

I encountered the problem, I know what is wrong, I just ran out of ideas how to solve it...
So, some time ago, I ran an update on the laptop, then I have not used it for a while. I dont know, if my kids were using it or what.. All I remember was, that after the update, I turned it off. And then fun has begun...
Grub was not working, So silly me, instead of running grub-mkconfig..... I dropped the nuclear bomb on my efi partition, reinstated grub, can log in to Arch again, but Windows 11 entry is gone.
I have done all the known to me tricks to have it back (os-probe etc) with no luck.
Then I realized, that I have lost .efi file for windows 11.
Unfortunately, all the trials to reinstate this file are deemed useless, I followed "Dual boot with windows" on Arch Wiki, but when I execute a command in DISKPART> assign letter=(let's say) G: , diskpart then requires volume assigning. So only available volume in diskpart is the one with Windows 11 on it, and i do not want to install it from scratch.

I remember having windows installed after linux on this laptop, and everything was working just fine.
There are also no Windows entry in laptop's UEFI boot settings.

I am just wondering.... how to make existing EFI partition to have dual boot again?
Just FYI, all of this because my kids decided to hibernate windows instead of switch it off completely, so I could not mount the partition in arch live environment - I can do it now but for the cost of losing access to win 11....... ehhh

Many thanks

So only available volume in diskpart is the one with Windows 11 on it

DISKPART> list disk
DISKPART> list vol

Arch Linux
