iCloud Drive has hit a very weird bug for me. I've used every Terminal and other solution. It stalls at a certain point—clearly a bad file or something. However, the Finder lacks good tools to pinpoint a fatal file. Does anyone know an Apple engineer I could send information to? It's clearly a combination of macOS and iCloud interaction. I can find other people with a similar problem online, but they typically solved it with one a number of techniques I've tried.
What I’ve tried:
• Delete and move lots of different files
• Log out of macOS account and back in
• Restart
• Disable and re-enable iCloud Drive (a huge pain)
• killall bird
• Delete ~/Library/Application Support/CloudDocs
