Does anyone know what might be causing the following error <RI.Hid> Failed to create device file: 2 The system cannot find the file specified. or perhaps how to fix Unity so this error doesn't continue to pop up. I am finding that leaving Unity run in the background for half a day while I am working on an asset in another program will cause Unity to crash. Even if the other software I'm working on is not a 3D Application and wouldn't be putting that much strain on unity. The only errors I seem to be getting with Unity are the one above and another related to cache expiring for a file titled 10.json I'm not sure if this is related to the problem but figure I should mention it incase it is of some relevance.
