Photos problem: library and iPhone flickers when I attach iPhone to MacBook Pro.
Photos flickers rapidly between library and iPhone when I attach iPhone to MacBook Pro. Using IPhone 11 and MacBook Pro OS 11.5 (Big Sur). When I plug my iPhone into my MacBook Pro using USB cord, Photos pops up and flickers over and over between Photos: library and the icon for my iPhone in Photos. All other open items freeze and can't be used unless I unplug the iPhone from my laptop. Photos says it is preparing to import. It does import eventually, and stops flicking back and forth but takes forever. Just started happening one day ago.
iPhone 11, iOS 14
