Hi,
As far as I'm concerned, the error message may due to the Windows Server 2019 VM version is too higher for the Windows 2012R2 host. Server 2012 R2 has no knowledge of Server 2019, nor the version of the Integration Components that it would have.
It's recommended to upgrade the Hyper V host System version, so they can have better compatibility.
Thanks for your time!
Best Regards,
Anne
