SteamVR acting weird in 4.18.3?

I am using 4.18.3 and SteamVR is acting really weird with this version.

First of all when I continueously play in VR preview, SteamVR is saying after a while that the UE4Editor is unresponsive.
But I can still VR preview no problem, the only issue is that my key input from my keyboard and controllers that i coded in BP are not responsive.
But when I exit steam and SteamVR and restart them, my key inputs work.

Something else that I saw when switching to forward rendering, is when I had to compile 7000 shaders. It took 20mins to compile roughly 400 shaders.
After turning SteamVR and Steam off, it started to compile shaders with 10 per second!?

Also in this version sometimes Matinee refuses to animate some tracks, which is different every time i go into VR Preview.

Are these bugs or just system related?
Its just so weird and makes no sense to me at all…

I think it may have been my own Steam VR acting weird, for some reason now it’s doing fine in UE4.
