Error with telerik url

I created a new project with Radzen Blazor Studio (first time installed). I have telerik devcratft installed on the same machine. When I tried to run the project, I get the following in the output window:
dotnet watch :fire: Hot reload enabled. For a list of supported edits, see Supported Code Changes (C# and Visual Basic) - Visual Studio (Windows).
:bulb: Press "Ctrl + R" to restart.

The build failed. Fix the build errors and run again.

What can I do to fix this?
