Hi,

I'm having the same experience. I need to debug further, but I guess it is related to the EasyAuth library:

Make sure there aren't any errors in the config file and the connection strings are set correctly.

I have seen this error come up some times, and to fix it I needed to Restart the App Service for the app and redeploy the code. There have been times where I had to delete the App Service Web App resource in Azure, and create a new one, deploy, and then it worked.

Here's the troubleshoot description Microsoft has in the docs for this error message:

The worker process fails. The app doesn't start.

The ASP.NET Core Module attempts to start the .NET Core CLR in-process, but it fails to start. The cause of a process startup failure can usually be determined from entries in the Application Event Log and the ASP.NET Core Module stdout log.

A common failure condition is the app is misconfigured due to targeting a version of the ASP.NET Core shared framework that isn't present. Check which versions of the ASP.NET Core shared framework are installed on the target machine.

I know this error is frustrating, but it's not related to any of the lab steps. There seems to be some times this error comes up when a .NET Core app starts up in App Service. Please let us know if you have any other issues with the lab steps. Thanks!
