It appears the blazor wasm publish is not happening. I'd publish to file folder and check the results. The blazor wasm publish should have added the blazor files to the wwwroot folder.
did you create the projects as explained above (with the core hosted option)? this is important because it adds the blazor wasm publish step to the server publish in the project files.
you can also try running, the blazor wasm publish. it should be a file deploy to the server bin wwwroot folder. then run the server publish.
