Concourse job: https://concourse.wg-ard.ci.cloudfoundry.org/teams/main/pipelines/cf-deployment/jobs/windows-deploy/builds/2220

The deployment was successful with the previous stemcell version:

value:
    alias: windows2019
    os: windows2019
    version: "2019.85

CF deployment should work with the latest windows2019 stemcell.

Start with the linked Concourse windows-deploy build and compare its Windows 2019 stemcell 2019.86 deployment with the previously successful 2019.85 deployment. Investigate the windows2019fs pre-start failure and confirm done when CF deployment succeeds with the latest stemcell.
