Bug Description

When trying to edit a file, claude crashes. the error states: Unable to resolve filesystem provider with relative file path

This is everytime it tries, to read a file before editing.

Expected Behavior

It opens and edits without crashing.

Actual Behavior

The whole nodejs application fails and dies

Additional Context (Console log):

● Perfect! I can see you have a basic .NET 9 Blazor project structure already. Let me add the necessary NuGet packages and update the project for our note-taking app with Azure Speech SDK and Markdown support.

● Update(NoteApp\NoteApp.csproj)
