Ошибка сборки для Asp.Net Core 3 (клиентская сторона Blazor)

Я начал разрабатывать веб-приложение с ASP.NET Core 3 и Blazor framework. В течение нескольких дней/недель я мог создать свое приложение. С момента анонса предварительного просмотра 5 я не смог собрать свое приложение (с помощью команды dotnet build). У меня следующая ошибка:

C:\Users\a\.nuget\packages\microsoft.aspnetcore.blazor.build\3.0.0-preview5-19227-01\targets\Blazor.MonoRuntime.targets(439,5): error MSB3073: The command "dotnet "" -l

Мой csproj выглядит так:

Я не понимал несколько дней, пока...
