Lightroom cloud updated in June 2020 and now gets frozen

I updated all applications in June 2020 (Lightroom, Lightroom classic, Photoshop),  and now when I open Lightroom,  it gets slow and does not show me my photos correctly and gets frozen thinking. Not sure why.  That never happened before the update. I am using MacBook Air.  Does someone have same issue or know whart can be happening?    thanks.
