Most mouse and keyboard inputs stopped working in Blender 2.80. How can this be fixed? I have had this issue previously and I have it again. Most inputs in Blender stopped working. I can't select objects or click most buttons and keyboard shortcuts aren't working either, neither does touch or pen on the tablet. I downloaded the newest release candidate and the issue is still there. I reset settings to factory settings and the issue still persists. What do i do? 
I have tried turning the computer off and on again.

Windows 10, 64 bit Blender 2.8 RC3

Solved it. Resetting to factory settings didn't help, deleting the 2.8 folder from appdata did.
If you have a rig in the scene, make sure you aren't in "pose" mode. If in pose mode you can't select the mesh just by clicking on it. You must switch to object mode first.
