Unity: DllNotFoundException: openvr_api

In my case, this was caused by having a VR project that I was running on a new version of Unity (2018.3.0f2) without having the OpenVR package installed.

Easy fix: Open the Package Manager (Window->Package Manager), select “OpenVR” in the package list and click install. Restart Unity
