Cubase 11 AI no reponse

Hello to all, when I was loading a project that takes about 30G of ram (my RAM is about 48G), Cubase stopped responding after the upgrade from Cubase AI 9.5 to 11. I used to load the project on Cubase AI 9.5 even if the samples exceeded my available RAMs, but this time it stopped responding even if there are still 10G of spare RAM.
I really appreciate any help you can provide.
