Windows – Boot Camp Assistant stuck on creating partition due to EFI formatted as NTFS

bootbootcampefintfswindows

Boot Camp Assistant is stuck on ‘create a partition’. I have followed the guide as answered in the question Boot Camp Assistance is stuck on create a partition? but it didn't work after step 8. After I clicked on the "Next" button it says:

Windows detected that the EFI system partition was formatted as NTFS. Format the EFI system partition as FAT32, and restart the installation.

What should I do?

You can try entering the following command in a macOS Terminal application window. This command should format the EFI system partition as FAT32.

sudo newfs_msdos -F 32 -v EFI /dev/rdisk0s1

If the command fails, you could try entering the command while booted to macOS Recovery over the Internet.
