Running into a really strange problem, which is completely blocking me from working in the editor.
When I launch the editor, and use an existing scene or a brand new project and scene, if I leave the editor alone and do something else for a bit, say use Maya, go on Facebook, whatever, and then return to the Unity Editor window, it completely locks up. Clicking on the UI doesn’t do anything, I can not interact with any menu, not even the Minimize/Maximize/Close buttons, nothing functions. The screen doesn’t even go white.
If I attempt to kill the process through my task manager, I can’t. After clicking “End Task”, the process still stays, and then attempting to do that again, it gives me a “Access is Denied” error, leaving me unable to kill Unity.
The only way to kill the process as far as I can see so far, is to do a full system restart. This makes the editor completely unusable for me, since I can’t do any work between different applications and Maya.
I have tried killing all non-essential programs while Unity is running and removing any external storage devices, and the problem still persists.
I am running the latest “stable” release, 5.5.0f3, on Windows 10. I have a GTX 1080, with the latest Nvidia Drivers. This is also a fresh install of Windows 10.
Has anyone else run into this problem? I have been unable to find a similar post/solution.
