Then, please check have you ever added the HttpClient service in the Program.cs or Startup.cs file. and inject the HttpClient service in the component?
Here is an article about Call a web API from ASP.NET Core Blazor, you can refer to it.
Besides, it still not working, try to create a simple sample and share it via GitHub or OneDrive, then we can check the code and try to reproduce the problem, then help you fix the problem.
