Screen position out of view frustum error?

Hello i am new to unity and my system has been running fine for a few months until recently where the editor screen is grey and there is an error that reads; Screen position out of view frustum (screen pos 142.000000, -1.000000) (Camera rect 0 2 633 622) UnityEngine.Camera:ScreenPointToRay(Vector3)

when i open unity the “screen pos” numbers very as i move my mouse across the screen getting smaller as the mouse gets closer to the bottom left corner does anyone know how to fix this?

If you restart Unity, the frustrum error usually goes away. It seems to be a Unity bug forcing a false positive error. If you press clear, you should be able to build and deploy.

I had this issue when I was setting my camera viewport rect to be outside of the [0,1] range.

Edit:
Scratch that, it was due to a !isNormalized error from setting Camera worldToCameraMatrix
