LR CC freezes

Hi,

I am using version 4.1 of Creative Cloud LR and I am experiencing times when the app/Mac freezes and I get the spinning coloured catherine wheel. My track pad doesnt respond then suddenly it works again but the control function I was using has changed?

Anyone else havng simular issues, I'm using an iMac with 32gb memory 4Ghz Quad Core i7 processor runing Big Sur 11.2 plus all CC apps are up to date!
