I just installed Mathematica. Everything worked fine and I am able to open a notebook, but when I try to calculate simple things (e.g., calculating the sum of 2 + 2) it says "running" for a few seconds then beeps and stopps the calculation. The output is: "The kernel Local has quit (exited) during the course of an evaluation". The same beep occurs when I open Mathematica, but there is no error message. I tried both restarting the application and my computer. I also tried reinstalling Mathematica. I am using Windows 10 and Mathematica 12.0. The Wolfram Kernel or the Math Kernel are both crashing immediately after launching.
