@Dipti-code Does your project contain a jsconfig or tsconfig file? Can you share these?

[diptilenka]

@mjbvz my tsconf.json is like

{
  "compilerOptions": {
     "target": "es5",
     "module": "commonjs",
     "baseUrl": ".",
     "paths": {
        "*": [
           "./*"
        ],
        "src/*": [
           "./src/*"
        ],
        "test/*": [
           "./test/*"
        ]
     },
     "types": [
         "node",
         "@wdio/sync",
         "@wdio/jasmine-framework"
      ],
      "allowSyntheticDefaultImports": true,
       "esModuleInterop": true
  },
  "include": [
   ["./**/*.ts"]
  ]
}

and also , my Vs code behaved abruptly, no intellisence or function hover not working

[diptilenka]

@mjbvz Any update on this.
and why its happening to my typescript project only that is created recently, not with other typescripts projects.

I converted the .js files to TS. am using typescript 3.8.3 and also my machine has also 3.8.3 installed globally./

@RyanCavanaugh Marking this as a VS Code priority since we've seen a few user reports of the problem

Please share the logs to be able to investigate this
You can upload logs by following these steps:

1. Set "typescript.tsserver.log": "verbose"
2. Restart vscode or vscode insiders
3. Reproduce the problem
4. In vscode or vscode insiders, run the TypeScript: Open TS Server log command
5. This should open a large file called tsserver.log. Please share this file. Additionally you can also share file ti.log created next to it.
