Error in Publishing .Net Core Web App on Docker Hub

I am learning docker and containers. I am trying to Publish my .Net Core 3.1 Web App on Docker Hub via visual studio 2019. I am on Windows PC, But the visual studio deployment environment is set to Linux and Docker also set to Linux. I have installed WSL2 (Windows subsystem for linux 2) as well. Also the Web app is executing well and at the same time I can see the container and image is created into Docker dashboard (running) successfully. However, while trying to publish it on Docker Hub, I am getting below error.

Can you help me out that which part is missing on my PC (it is azure windows 10 VM)?

Note: I am able to run linux containers as well without any issue. Also Ubuntu 20 is installed from Windows Shop.

Change desktop-linux

{
  "auths": {},
  "credsStore": "desktop",
  "currentContext": "default",
  "stackOrchestrator": "swarm",
  "HttpHeaders": {
    "X-Meta-Source-Client": "vs/web/publish"
  }
}

currentContext had desktop-linux, I just put "default"
