iCloud Error message Cannot communicate with helper application
I have a MacBook Pro (Retina, 13-inch, Mid 2014) with 8 GB RAM 250 GB storage, mac OS Catalina version 10.15.7 . I am trying to free up space for installing the update. While I can store my desktop and documents in my iCloud, I cannot do so with my photos. I get an error message saying "Cannot communicate with a helper application". This persists on multiple retries, including restart in safe mode etc. Please advise
