Got a fix / workaround from Oculus Support today and in my case Fixes my "Arktika.1 has stopped working"
Here it is, give it a go. it affects desktop/laptops with 2 graphic cards, i my case on my laptop I have a Intel HD Graphic 530 and a Nvidia GTX1070. The issue was that Arktika, unlike all my other VR titles picks the wrong graphic card (the Intel one) To force Arktika to used my Nvidia card you need to run the Nvidia Control Panel->Select Manage 3D setting->Select "Program Setting" Tab on the right->Look in the drop down list for Arktika1.exe, if not found click the ADD button and browse for the Arktika1.exe (it will be found in your Oculus Library folder) -> Then select which processor to use, I my case "High performance Nvidia processor"-> Then click APPLY button
Hope this works for you.
