The Paragon NTFS driver is probably having conflicts with your Mac's native NTFS driver, preventing the BootCamp partition to show up in the startup disk. You can try uninstalling it to see if the issue is resolved.
If not, or you need an NTFS for Mac tool to write to the Boot Camp partition on Mac, use iBoysoft NTFS for Mac instead. It can automount your Boot Camp Windows partition and NTFS-formatted external drives in read-write mode, allowing you to work with NTFS drives on Mac freely.
