Boot Camp error “Windows cannot locate the disk and partition specified in the unattended answer's file”

I have a 2019 MacBook Pro 16 inch running on macOS Big Sur 11.1. I am trying to install windows using Bootcamp. I get the following error:

Windows cannot locate the disk and partition specified in the unattended answer file's < ImageInstall > setting. Make sure the setting references a valid partition and restart the installation.

Attached the image of my disk utility without Bootcamp partition and the Image of the error.

Can someone help me how to solve this?

Thanks in advance

MacBook Pro 16″, macOS 11.1

BC Assistant is failing to create the correct Windows Installer partition (OSXRESERVED).

Can you run a SMC and NVRAM Reset and try?
If that does not work, can you create a Time Machine backup of macOS?

Apple store will not install Windows. Did this Mac originally come with Big Sur?
