I've been working on this problem for over 10 hours. First of all, I installed Mojave using the Mojave patcher on an older MacBook (The model number is A1278. It's a 2011 Macbook Pro) I completely erased my disk before installing Mojave. Here is the output of diskutil list:

and sudo gpt -r show disk0:

Why am I still getting this error when I run boot camp assistant? I've already followed a guide that involved deleting any hidden Microsoft files in the EFI EFI partition. But I don't think it really did anything because as I said, I completely erased this disk before installing Mojave. I'm at a complete loss here, and I'm desperate for help.
EDIT: I know this question has been asked before, but from what I can tell, no one has had this exact problem. On the posts I see involving this problem you can clearly see Microsoft partitions in the diskutil list. I have no visible Microsoft partitions. I performed a clean install. So I'm at a loss for why I keep getting the error.
I used GPARTED to format the SSD and then reinstalled using the macOS Mojave Patcher ( http://dosdude1.com/mojave/#additional_info ), and I still have the same problem. I don't know what else to do.
