Unity freezeed with log file ended "Enlighten: Bake started." No response anymore.

I am a Unity beginner. I have used Unity 2018.2.14 for some days and today I updated it to 2.18, then I found i can't open any project.
Every time I open a project, the window goes frozen. No response, I can do nothing but kill the process from task manager.
I have tried several methods:
1: reinstall 2.14 , 2.18, LTS 2017 version.
2: restart the computer.
3: clear all my unity settings.
None of them works.
My Editor.log ends:

Nothing more.
I use a laptop, the parameters are:
windows 10 64 bit
Direct3D:
Version: Direct3D 11.0 [level 11.1]
Renderer: NVIDIA GeForce MX150 (ID=0x1d10)
Vendor:
VRAM: 1983 MB
Driver: 23.21.13.9125

It is not a high performance computer, but it works well with Unity the days before.
And the problem occurs even when I try to create a new project.
How can I resolve this?
Please, I have been bothered almost all the day.

Updates:
I find that my computer is Hybrid Graphics, and when I start the Unity with my Intel® UHD Graphics 620, it works well. But with the NVIDIA GeForce MX150 it does not work.
I try to uninstall and reinstall the NVIDIA GeForce MX150 driver. But the problem still exist.
My driver assistant does not detect any error.
Emmm, it seems like I should go to Intel website for support......

 

NVidia makes the MX150, not Intel, so I would try an NVidia forum.
