UE4 crashing on engine startup (Loading project) Assertion Failed: LocalOwningNode

Hey everyone, Has been cruisy until today with Epic’s update to the launcher, since then I have had the Ikinema plugin not responding and vive controllers not tracked, intermittantly they worked but the Steam VR chaperones were way out of whack, then they worked once and now it won’t load the project at all.

Logs attached:
