(XBOX) CAS is becoming impossible

Whenever I enter CAS now, as soon as I click anything my cursor disappears and I can never get it back therefore I can't do anything. When I open my game menu in CAS I can't get off of it either, meaning after hours of progress in CAS the only way I can get out of it is exit to my XBOX homepage, the game wont even let me exit to main menu so I have to reload the game which for me literally takes 20 minutes??? CAS also says im in a tutorial when im not - meaning I can't get any access to the gallery or ANYTHING else!!!!
