I have an issue where when I go to install Bootcamp, I try to format the drive and it comes up with this error message:
"Your bootable USB drive cannot be created."
I have my ISO image and my USB drive (16GB) connected to the computer, but it still comes up with this error message. I am also running on macOS Catalina and I can't upgrade it because my system is too old. If anyone can assist me with this issue, thanks.

Yes, I am erasing it and formatting it into MS-DOS (FAT), however every time I try to format it with bootcamp, it goes back into ExFAT.
The USB2 installer must be exFAT for macOS versions Mojave and higher. This accommodates Microsoft W10 1903 and newer ISOs.
The USB2 installer should be managed by BC Assistant. Manually erasing/formatting will lead to new issues.
Yes, I originally followed the steps of Bootcamp and started from ExFAT, but I tried many things which are not working. Anyways, here is that output:
So, essentially, I still can't seem to install Windows and it gives me the same error message. Are there still no fixes?
Your external disk3 should be formatted using the following command...
diskutil eraseDisk exfat WININSTALL MBR disk3
The current format is invalid for use as a W10 installer. Let BC Assistant handle erasing/formatting this disk in future attempts.
You have a 2Tb Fusion drive, which can be corrupt. As a test,, in Disk Utility, create a FAT partition (not an APFS volume), of the size you want Windows to be. Expand the Detail section and post the output.
Do you have a backup of macOS and all your files?
