Bootcamp error message: Unable to read the Windows partition

Hi there,


I was wondering if anyone could help me with the following question. When I press the first continue button on bootcamp, it provides me with the following error message.


Unable to read the Windows partition

Boot Camp Assistant was unable to verify if the Windows partition contains a Windows installation. This may be because BitLocker is enabled on the partition. If so, disable BitLocker on the disk before removing Boot Camp.


If anyone could help me, it would be greatly appreciated.

Notice you have two Bootcamp entries - a partition and and APFS volume. The APFS volume will not work. Is this a new installation of Windows?
