So I've spent at least an hour and a half installing Unity through the Unity Hub app. When starting a new project the editor takes 10 minutes to load, and when loaded, all I see is a gray/black screen... It worked flawlessly when I installed it a few months ago... on the same machine!! This is a fresh install (I had to format my PC). I'm using Unity 2019.2.11f1 in a 64bit Windows 10 machine, 8GB of RAM and an Intel i7 processor. I've looked this up and found no solutions to these two problems... Please help??
