I have the same error with 0.16 but you can download the 0.15 version in lovr historial (Acces at the botton of the download page) and it works.
I can't see my hands with my Valve Index, I'm looking if I need to enable some extra configuration.
The correct lovr version for different operating systems can be found at the bottom of this page: lovr v0.15.0 (Government Goop).
I’ll update the description. Thanks for your interest.
