Boot Camp installation failed at macOS Mojave - "An error occurred while copying the Windows installation files"

Hello,

I have a MacBook Pro Retina 2016 with macOS Mojave and I was trying to install through Boot Camp a Windows 10 ISO I downloaded from Microsoft: Win10_1809Oct_English_x64.iso

I have never done this before or partitioned my disk (APFS).

Halfway through the installation, it failed with the following reason: "An error occurred while copying the Windows installation files". The ISO is located in ~/Desktop and it wasn't mounted before installation.

Has anyone faced a similar issue or knows what the problem is?

Thank you.
