Windows 10: BSOD - Error Code 0xc000021a

Over the past couple of weeks, my computer has been bluescreening with the error code "0xc000021a" each time. At first I thought it was something that could be fixed with a simple hard reset of my computer, but unfortunately, it later bluescreened again. It seems that each time it bluescreened was when I woke up in the morning and first turned the computer on, even thought I had no issues the nights before turning the computer off before bed. After resetting the computer to a restore point and redownloading some small things, I found out that I can restart my computer with no problem once ag
