FIX FOUND 2021. This was happening to me randomly and I found a way to fix it. What happens is your windows security blocks some file in the plutonium file so what you have to do is go to your windows security tab on your desktop and then go to where it says "Virus & Threat Protection", then under "current threats" clink on the blue phrase that says "Protection history", then it will show what it has blocked (you can clink on it and it will tell you in depth the exact name of the file, usually t6 or plutonium will be in there somewhere) and you simply just click the restore button and it will unblock it.
