Sketchup (not responding)

Sketchup wont start, toolbars load and it stops and says “sketchup (not responding)” at the top. Drivers updated windows updated very occasionally opening a skp file will open straight away but not often (once every 2 weeks). I have a gaming laptop Asus ROG i7 Nvidia GTX 970M when it works its great but it wont start

Did you double-click a SKP file when trying to start it ?

Did you install any new extensions lately ?
