[Solved] Grub can't find ESP (Dual Boot installation with Windows)

Hello there, I am having troubles installing Arch on my Laptop. Previously my Laptop was running a dual boot setup with Windows 10 (clean installed) and latest Kubuntu. It also already had Grub installed. Now I want to change Kubuntu to Arch Linux with KDE and I still want to dual boot Windows. I am following the Beginners guide, the installation guide, and have watched some videos in advance. But when it comes to setting up grub, it always fails. My EFI system partition, which was originally created by Windows installation, is sda2 and if I mount it at /boot, following error occurs, when I try to setup grub:
Cannot open /boot/grub/device.map (the file does not exist). It also says: "Failed to get canonical path of esp". I double checked btw, that the boot flag for sda2 is set.
Here is the command, that produces the error:

grub-install --target=x86_64-efi --efi-directory=esp --bootloader-id=grub

Sometimes they say on the internet, that you should mount at /boot/efi, but when I do this, it produces even more errors. Grub reports similar errors and in addition to this, also initramfs doesn't work anymore, so I suppose that is not correct.
What do I have to do now?

Not an installation issue, moving to NC.

Are you running this from your root directory? If not the flag should be '--efi-directory=/esp' (with the forward slash at the start), assuming you've mounted your ESP on /esp - could you post the output of running "mount" to confirm that it is mounted correctly?

Well, you might use actual directory instead of esp. If you've been reading the wiki on grub, might want to read it more carefully. You are supposed to replace esp with the actually path to the location where your EFI system partition is mounted.

Sry for late reply
Thank you for the answers, it actually just was that I had to replace esp with the directory and now I have a stable Arch Linux installed
Stable, except that it sometimes does not shutdown when I press shutdown. Instead it says that there is a stop job running, waits 90 s and then shutsdown.
How can I fix this? The internet says that I should downgrade systemd, but is that really recommended?

Edit: I found the solution, in case it is useful to anyone:
Just run this command to disable coredump:

ln -s /dev/null /etc/sysctl.d/50-coredump.conf
