Unable to share drive with container

I am attempting to enable volume sharing through the Docker Desktop for Windows Settings window, but Docker is reporting that it is being blocked by the firewall. What is the appropriate way to allow sharing between containers and the host?

I’ve verified that firewall is allowing all traffic from all Docker executables.
C:\Program Files\Docker\Docker\resources\com.docker.proxy.exe
C:\Program Files\Docker\Docker\resources\Docker Desktop Installer.exe
C:\Program Files\Docker\Docker\resources\bin\docker.exe
C:\Program Files\Docker\Docker\Docker Desktop.exe
C:\Program Files\Docker\cli-plugins\docker-app.exe
C:\Program Files\Docker\cli-plugins\docker-buildx.exe
C:\Program Files\Docker\Docker\com.docker.service

There is an SEP rule in place to allow inbound requests on the local subnet on port 445.

Whenever I attempt to enable Shared Drives through Docker settings, I see the following entries in the log:
