vscode: All breakpoints are unverified

• VSCode Version: 1.28
• Node Version: 10.12
• OS Version: Windows 10 1803
• Using Typescript: No
• Using Webpack: No

Launch configuration

{
  "type": "node",
  "request": "launch",
  "name": "Launch Program",
  "useWSL": true,
  "program": "${workspaceFolder}\\index.js"
}

Steps to Reproduce:

1. Add breakpoint which appears as a red filled circle
2. Launch with above configuration
3. Breakpoint turns to gray outline with hover of ‘Unverified breakpoint’
4. Insert debugger; statement in code
5. File opens with subtitle ‘read-only core module’ in the titlebar
6. Add breakpoint to this read-only file. This breakpoint works as expected
7. Remove debugger; statement in editable source file
8. Add functioning breakpoints in the read-only file as required. They all work perfectly.

Line of Examination:

1. Disabling sourceMaps in the launch configuration didn’t work
2. "localRoot": "${workspaceFolder}" and "remoteRoot": "C:\\Users\\user\\folder" did nothing. Code still opens in separate read-only file
3. Opening entire folder in Ubuntu and running launch as-is works perfectly. No issue with breakpoints at all.

I have been struggling with this issue since at least July 2018 without finding a working solution. I would be very grateful for help, since I have to go back to inserting console.log statements all over my code.

Does this issue occur when all extensions are disabled?: Yes
