dual boot not work after reinstalling archlinux

Before reinstalling archlinux, systemd-boot can dual boot archlinux & Windows 11.
When installing archlinux, /dev/nvme1n1p1 and /dev/nvme1n1p2 are reformated.
After reinstalling archlinux, disk partitions are as below, it seems that efi for booting Windows has been lost.

Device              Start        End    Sectors   Size Type
/dev/nvme0n1p1       2048      34815      32768    16M Microsoft reserved
/dev/nvme0n1p2      34816 1999087615 1999052800 953.2G Microsoft basic data
/dev/nvme0n1p3 1999087616 2000406527    1318912   644M Windows recovery environment

Device             Start        End    Sectors  Size Type
/dev/nvme1n1p1      2048    2099199    2097152    1G EFI System
/dev/nvme1n1p2   2099200  106956799  104857600   50G Linux root (x86-64)
/dev/nvme1n1p3 106956800 3907027119 3800070320  1.8T Linux filesystem

Any way to make dual boot work again without reinstalling Windows?

Re: dual boot not work after reinstalling archlinux

windows-specific question about how to restore it: not support here (but there are multiple)
general: you seem to have used archinstall instead of doing it manual - which has shredded your existing setup
hint: archinstall is no noobtool as a replacement for the manual way but a tool for experienced users
