Bootcamp Error: "Your disk could not be partitioned". Windows 10 installation

Hi,

I have been trying to install Windows 10 on my MacBook Pro Retina 13 2017 running Mojave 10.14 with no success.

I get the error: "Your disk could not be partitioned".

After some research on the web, I have already tried:

- Check that FileVault is disabled (it was).

- Disable Time Machine.

- Delete Time Machine local snapshots with DaisyDisk.

- Delete Time Machine local snapshots with Terminal > tmutil thinlocalsnapshots / 9999999999999999

- Reboot in Single User Mode (Cmd + S) and /sbin/fsck -fy

- Reboot in Single User Mode (Cmd + S) and fsck_apfs -s -o -y /dev/rdisk1

When I run Terminal > "diskutil list", I see a "4: APFS Volume VM 1.2 GB disk1s4". See output below. I deleted Parallels when I decide to switch to Bootcamp. Does "APFS Volume VM" (VM = Virtual Machine?) mean that I haven't uninstalled Parallels correctly? Can/should I delete disk1s4? How?

When I run Terminal > "sudo fsck_apfs -n -l /dev/rdisk1", I get a "warning: found orphan file extents (id 328, size 85159936)". See output below. How can I fix this?
