Unhandled Runtime Error
Error: invariant expected layout router to be mounted
Call Stack
OuterLayoutRouter
My imports are from "next/navigation"
The directory structure is correct - hasnt been changed from what the installation has provided
I've tried the suggestions made by copilot chat which include Ensure the GeistSans import is correct: Make sure that GeistSans is correctly imported and used in your layout file.
Check the directory structure: Ensure that your directory structure follows the Next.js 13+ conventions. The layout.tsx file should be in the app directory or a subdirectory within app.
Verify the page.tsx file: Ensure that you have a page.tsx file in the app directory or a subdirectory within app.
Check for any missing dependencies: Ensure that all required dependencies are installed and up-to-date.
Simplify the layout for debugging: Temporarily simplify your layout.tsx file to isolate the issue.
