Docker Daemon won't start following Windows Build Instructions

I’m trying to build the Windows binaries and start testing some small changes, but docker daemon will not start.

PS >.\dockerd.exe

Error starting daemon: error while opening volume store metadata database: timeout

In addition, when I start up the stable version, the service starts, but the daemon is unresponsive. There’s no error that I see. I have to Reset to factory defaults to get the stable version to start cleanly.

error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.32/version: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.

I’m not finding much information in this forum or GitHub issues to point me in a direction to troubleshoot.
