Urgent : Completely Broken Unity?

Okay I was happily composing a scene, then bam, the camera wouldn’t rotate in scene view and I’m getting the message in console

transform.rotation assign attempt for ‘SceneCamera’ is not valid. Input rotation is { NaN, NaN, NaN, NaN }.
UnityEditor.DockArea:OnGUI()

This just keeps getting printed out. I’ve tried a new project from scratch with no assets in it and the same thing happens,

Now I cannot rotate my camera in scene view at all! switch from iso to perspective works but it stays on the same rotation and trying to move to top, left, right etc does nothing. This is quite serious I cannot navigate the scene view at all, pls help UT!

Many thanks

Im not sure how to fix this. But I would uninstall/reinstall Unity

I uninstalled and reinstalled unity but this didn’t fix anything I was still getting the same message, I was trying all camera movement controls right click with wasd, alt and left/middle/right click, framing objects with F and nothing, it would move but never rotate and kept spamming that message… so i went a bit postal and just start clicking dragging and hammering the keyboard and all of a sudden it just came back to life so I have no idea what I did but I fixed it
