"mount: /boot/EFI: unknown filesystem type 'vfat'." during installatio

Hey, I'm trying to install Arch in a pretty standard way. I'm in chroot, mounted /boot, I want to mount EFI to /boot/EFI and this is what I'm getting:
```
[root@archiso /]# mount /dev/nvme0n1p1  /boot/EFI
mount: /boot/EFI: unknown filesystem type 'vfat'.
       dmesg(1) may have more information after failed mount system call.
```
Dmesg doesn't show any related message.

Initially the EFI partition has been created by Windows, but thinking that it might be broken, I create a new one of size 512M using ` mkfs.fat -F 32 ` and got the same issue.

Any idea how to proceed?
I'm installing from live iso downloaded today:
```
[root@archiso /]# uname -a
Linux archiso 6.12.1-arch1-1 #1 SMP PREEMPT_DYNAMIC Fri, 22 Nov 2024 16:04:27 +0000 x86_64 GNU/Linux
```

Did you update the ISO, ie run pacman -Syu? For some reason, there are people that do that and it would cause this.

Edit: wait, you already chrooted. Mount before chroot.

You were right. A restart helped. Probably I updated the ISO accidentally.
