Blender 2.8, missing keymap settings after installation of blender 2.8 I cannot click on anything in the 3D view and the outliner tree structure. Besides all shortkeys are not working at all.

In the Settings of blender 2.8, the whole Keymap tab is empty. I reinstalled it and even tried to use the non install version - this problem still remain... (OS clean Windows 10 x64)

Any ideas :D ?
I had this same issue.
I discovered I had two versions of python installed and after deleting the oldest version, my issues were resolved. Do the same and hopefully it works.

To check if you have multiple versions of python installed you can go to the command prompt window and enter C:\Users\YourUserName>py -0 and it should list all your current installs.
