runtime error with webapi project can't find Microsoft.AspNetCore.OpenApi

[relcodedev]

I created a new project with dotnet new webapi -o webapiapp. I know that the example only uses web project. Is webapi supported? The dll Micrsooft.AspNetCore.OpenApi.dll is in the output folder.

        var builder = WebApplication.CreateBuilder(args).UseWasiConnectionListener();

        // Add services to the container.

        builder.Services.AddControllers();
        // Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
        builder.Services.AddEndpointsApiExplorer();
        builder.Services.AddSwaggerGen();
        builder.Services.AddApiVersioning();

        var app = builder.Build();

        // Configure the HTTP request pipeline.
        if (app.Environment.IsDevelopment())
        {
            app.UseSwagger();
            app.UseSwaggerUI();
        }

        app.UseHttpsRedirection();

        app.UseAuthorization();

        app.MapControllers();

        app.Run();

dotnet run gets error:
