cubase 10 takes over 30 minutes to intalize

each time I try and start Cubase 10 its takes ages to actually get to the main menu.it starts to load fast then it get to the initializing content load library then it goes very very slow…its saying theres 162 and can take anywere from 30 mins to nearly a hour too scan it and it does this everytime I try and start Cubase.

my computer is pretty fast and Cubase 9.5 loaded it in under a minute before .

anyone know how to fix this?
