Pitch Shift not loading Cubase 11

Hi all I am a complete newbie… I have Literally just started learning with “The Ultimate Beginners Tutorial” Videos. Everything going fine til video 2 yes TWO!! for some unknown reason I cannot use pitch change! It has a blue, whirly, loading circle over it and stops me from changing up to continue my learning…
Any rescuers out there?
