When I am installing Windows 10 after I format the Bootcamp partition, I receive the following error message:
"Windows detected that the EFI system partition was formatted as NTFS. Format the EFI system partition as FAT32, and restart the installation"
I am not sure what is going on. I have the latest Windows 10 ISO image and my system is completely up to date. USB drive is formatted to exFAT.

Once you run Create+Download, you do not need to run it again. Install should be run only once. If it fails, any extraneous partitions should be cleaned, SMC and NVRAM Reset, before the next attempt.
Do the EFI NoName partitions need to be removed?
Yes, otherwise you will not be able to install Windows.
Run
dskutil eraseVolume free free disk0s3
and repeat this command for disk0s4 through disk0s15. Post the output of
diskutil list
before we go further.

Each EFI NO NAME partition is indicative of a failure. This typically indicates attached external storage during Windows installation.
Your Mac should have there options in BC Assistant - Create, Download and Install.
iMac 27-inch Late 2013
MacOS Catalina version 10.15.4
After bootcamp finishes the drive partition the computer reboots and automatically loads the windows install and I get the error code. I have tried to manually load it by using the option key, I have even tried creating the USB drive manually without the help of Bootcamp but I still get the same error .

What is the year/model of your Mac (do not post the serial number)?
What is the current macOS version?
Are you manually interrupting the installation process and selecting EFI Boot?
Your 2013 iMac is a UEFI machine. Do you have a Fusion drive? Can you post the output of
diskutil list
from macOS Terminal?
I have been through those steps many times. Do the EFI NoName partitions need to be removed?
Thank you so much! That solved my problem. Perfect install after clearing those out.
Can you post the output of
diskutil list
We should check if all your disk space is allocated properly.
