Bootcamp difficulty: Windows cannot locate the disk and partition specified in the unattended answer file's setting.

I tried installing Windows 10 Home through Bootcamp and it keeps telling me "Windows cannot locate the disk and partition specified in the unattend answer file's <ImageInstall> setting. Make sure the setting references a valid partition and restart the installation.

I've been at this for 2 days now and it's starting to worry me. I really need the Windows OS to run some games and apps.

I've called support and looked online and nothing has helped so far. I even reset my iMac by wiping the drive through Disk Utility and it still didn't work. ( I could not reset it normally because it kept mentioning some partition even though I had removed my BOOTCAMP partition.)

My iMac is running Sonoma 14.3.1.

I've confirmed the boot setting is set to full security.

I made sure that while partitioning, that MacOS had a total 64 GB.

My iMac model identifier is iMac20,1.

I'm really getting desperate for some help.
