EFI Partition gone after booting into Windows 10

Hello! I have Windows 10 on a SSD and Arch on an other SSD. But, when I boot into Windows 10, it removes the GRUB EFI Partition. After that, I have to reinstall GRUB on the EFI Partition. I don't know why this happens. It seems I'm the only one with this problem because couldn't help me.

Thanks.

I doubt it's being removed from the ESP. More likely your firmware is removing the NVRAM entry when you choose Windows.

I find that hard to believe. How are you checking for this? Do you have any diagnostic command output to share?

Some UEFI firmware implementations have a habit of "forgetting" stored NVRAM boot entries and that might explain why you have to create a new one for Arch.
