• Your Windows build number: (Typever at a Windows Command Prompt)
  Microsoft Windows [Version 10.0.16278.1000]

• What you're doing and what's happening: (Copy&paste specific commands and their output, or include screen shots)

• $ npm run build (getting errors)

• getting erros
  

• $ npm run build (running it again magically fixes it!)

• magically fixes it
  

• What's wrong / what should be happening instead:
  Similar to my issuesometimes I have to invoke the command twice to register #2494 ; This build is a hit or miss, sometimes I need to run the same script 3x to 4x just to get it running. I have my Defender Off.

Seems to me that it can't reach/read the node_modules, looks like another File I/O Issue?
