while running a Node.js application packaged with `pkg` from bat file using the following command,

```plaintext
start "" "mynodeapp.exe"
```

the issue is related to the application trying to modify the process title, which causes conflicts in certain environments (e.g., Windows).

#### **Fix:**

To resolve this, change the way you launch your `.exe` file by using the `start` command with a title:

```plaintext
start "MyAppName" "mynodeapp.exe"
```

This simple fix provides a title for the process, allowing it to run without the error.
