package.json dependencies

"dependencies": {
    "vue": "^3.5.13"
  },
  "devDependencies": {
    "@vitejs/plugin-vue": "^5.2.1",
    "typescript": "~5.6.2",
    "vite": "^6.0.1",
    "vue-tsc": "^2.1.10"
  }

Steps to reproduce

1. Create a new project using npm create vite@latest vue-example2 -- --template vue-ts and have the VSCode extension Vue - Official installed.
2. Open ./src/components/HelloWorld.vue and restart VSCode
3. The file should be open automatically and the Vue Language Server should be up and running. Type information is showing on hover.
4. Close the file and reopen VSCode
5. The file should not be open
6. When opening ./src/components/HelloWorld.vue the Vue Language Server is in a broken state and doesn't show type information.

What is expected?

The Vue Language Server should run regardless of the action order.

What is actually happening?

The Vue Language Server is in a broken state and doesn't show type information.

My work-around, when I see that the component tag syntax highlighting has not activated for a .vue file, is to run "Developer: Reload Window" from the command palette. Rather annoying.
