This looks to be an issue in BashOnWindows and not ansible or ansible-vault.

On Sat,
Anybody using vault with windows linux subsystem?
I get this if I try to do anything requiring the vault:. I've down apt-get
update and upgrade. openssl is 1.0.2g.
c1rpc@LOUIS:~/cartewright$ ansible-playbook -i inventory
check_inventory.yml -vvv
No config file found; using defaults
