Containers failing to create in Windows node of Kubernetes

Hi Team,

I am having a heterogeneous(Linux + windows nodes) Kubernetes cluster with version 1.15.3. The windows node was added to the cluster. When I am trying to spin up a pod in windows node, it is stuck in ContainerCreating status. When I describe the pod I am seeing the below error.
I manually added /run/flannel/subnet.env in master node, as I received /run/flannel/subnet.env: no such file or directory error.

Error: NetworkPlugin cni failed to set up pod “hello_default” network: /run/flannel/subnet.env is missing FLANNEL_NETWORK

You have to remove (or rename) that container to be able to reuse that name.

Can someone please help me to fix this.

Thanks,
