Solution

  • Since this was not reproducible by others & it was fixed automatically for me - i am answering this question.

    I have tried multiple times to compile but it didn't work, so i have commented out the piece of code & keep working on others changes. Today i tried again after seeing some comments and it was fixed. I am really not sure what happened.

    If you are experiencing this - Please do a restart of your computer.

    Hope this helps other people.
