Parallels can't find installed, working W10 Boot Camp partition

I have scoured posts, forums, and discussions and can't find a solution to this. Many similar issues, but nothing that solves my problem.

I purchased a new, 2019 MBP and immediately installed W10 through Boot Camp after doing the initial setup of the MacOS. Later, I purchased Parallels and attempted to put my installed W10 Boot Camp partition in there using the directions listed here: https://kb.parallels.com/112941. My Boot Camp partition is not found when viewing Configuration > Hardware > Hard Disk 1 > Source.

Looking in DiskUtil, I have two internal partitions (both on the same SSD): 'Macintosh HD' and 'BOOTCAMP'. The Boot Camp partition is grayed out, likely due to it being unmounted. Right-clicking the name and choosing 'mount' has no response. Selecting the 'Mount' icon right below the Disk Utility header also does nothing. Trying to mount from terminal using 'sudo diskutil mount /dev/disk0s3' responds with 'Volume on disk0s3 failed to mount. If the volume is damaged, try the "readOnly" option."

Any ideas of where to go from here? I've seen many posts about Paragon and similar tools; I do not and have not had these installed. Thanks in advance.

I have not installed any third-party NTFS products on this MBP. I tried mounting the partition as it was mentioned in a troubleshooting forum post to mount the partition if it was not showing in Parallels as a source option.

Windows does work properly when booted through Boot Camp. I use it in Windows 99% of the time for 10+ hours on working days; never had an issue.

I uninstalled Parallels last night and have not reinstalled it. I do not believe there were any additional utilities installed. How do you use the Apple specific NTFS driver to mount it? Just go to Disk Utility and mount from there (that doesn't work)?

Thanks for helping so much with this. I'm still waiting to hear back from Parallels Support.

devfs on /dev (devfs, local, nobrowse)
/dev/disk1s4 on /private/var/vm (apfs, local, noexec, journaled, noatime, nobrowse)
map -hosts on /net (autofs, nosuid, automounted, nobrowse)
map auto_home on /home (autofs, automounted, nobrowse)

How to reinstall macOS from macOS Recovery - Apple Support on an external disk. It should match the same version as you have on your internal disk. Do not use a Time Machine to build an external bootable disk.
