Unable to boot into Win11 from GRUB.

After the arch & grub installation, went to install win11, went well. After regenerating grub.cfg while it found bootmgfw.efi, tried booting from the new entry in GRUB, but it only shows the logo for a second and reboots the system. I've tried: regenerating the BCD boot in windows, re-regenerating the grub.cfg, as well as installing grub, resintalling windows, doing clean startups on windows. Tried the win utility to "repair boot" but didn't found an error. Arch boots fine. No info online. Forgot to say: I can boot into windows from the UEFI boot menu.

I know this might not be the place to ask, but I might find the answer. Hoping to get confirmation that GRUB is properly installed (a UEFI/GPT partition on GRUB, Arch and Windows), so it'd be a windows block on GRUB or something alike.

Grub ver is 2.12.

There's a whole dedicated wiki on dual-booting with Windows. Have you had a read of it?
