Hi Megan,
Thanks for your reply. Well, this happens a few minutes after I launch the sandbox from the academy’s webpage. The computer freezes completely and becomes irresponsive and I have to turn it off using the power button. I have never had a similar issue before, and it is not a bad computer. Also, I tried using Edge instead of Chrome, which what I was using before, and I still got the same problem.
Thanks,
Mohamed
