Can’t load windows after dual booting with Manjaro – Installation & Boot

I dual booted manjaro KDE into my Razer blade 15 2021 advanced model. Windows had already created a efi boot partition of 100Mib already, So I mounted into that using /boot/efi. But I cant boot into windows now. It shows up in my grub, and once I select it, it crashes with the blue screen and error message.
Also my nvme drive is also not recognised in bios. Manjaro loads fine.
os-prob is not disabled and fdisk -l shows all my partitions properly.

Any help on this is much appreciated.
