I have set render mode globally in App.razor
<Routes @rendermode="InteractiveServer" />
<!DOCTYPE html>

After I have done that, I get this error
InvalidOperationException: A second operation was started on this context instance before a previous operation completed. This is usually caused by different threads concurrently using the same instance of DbContext. For more information on how to avoid threading issues with DbContext, see https://go.microsoft.com/fwlink/?linkid=2097913.
