Yesterday everything was fine. Today, every new/fresh project created with Visual Studio 2019 Preview is broken and it's showing only Loading... in browser.
Error in Google Chrome ver. 72.0.3626.109

Failed to load resource: the server responded with a status of 404 (Not Found)
components.webassembly.js:1 Uncaught (in promise) SyntaxError: Unexpected end of JSON input

It doesn't matter if project is clear Blazor or Blazor (ASP.NET Core hosted). I didn't change anything. I just create a project and hit run on IIS Express button on top of VS.

dotnet --version

Blazor ver. 0.8.0
Latest ASP.NET Core Blazor Language Services

dotnet build - no errors
dotnet run - same behavior as build in VS.
