Describe the bug

Creating new files in the Next.js app produces linting errors in VS Code. Only workaround is restarting the editor.

Link to reproduction

https://github.com/t3-oss/create-t3-turbo

To reproduce

Clone the stock repo using the CLI command from the docs:

npx create-turbo@latest -e https://github.com/t3-oss/create-t3-turbo

Open in VS Code:

cd ./my-turborepo
code .

Create a new TS file anywhere in the apps/nextjs/src directory:

code apps/nextjs/src/test.ts

Save the empty file. Observe the red tilde under the cursor, which provides the following error:

Parsing error: [path]/my-turborepo/apps/nextjs/src/test.ts was not found by the project service. Consider either including it in the tsconfig.json or including it in allowDefaultProject.eslint

Additional information

Restarting the TS server does not help. Only workaround I can find is restarting VS Code entirely.
EDIT: I can also close and re-open the workspace instead of restarting the editor.

I have similar problem in my next.js project with eslint flat config.

Faicing the same issue, had to restart VS code.

Seems the issue is upstream but typescript-eslint 8.3.0 might fix the issue
