iCloud Drive sync stuck

I ran into the exact same problem like some other people here. After clean-installing Monterey to my two machines yesterday (MacPro 6.1 and a MacBook Pro 15" Late 2015) my iCloud Drive got stuck syncing on both machines! If I try to copy folders within the folders in iCloud Drive (documents / desktop / etc.)I get this Error: **Finder cannot complete the operation because some data in “” cannot be read or written Error -36** If I click on a folder's cloud icon to download it it says **folder "" can't be downloaded check your internet connection**. But I am online, no ports are blocked. Copying files is not a problem! Just folders. When I deactivate iCloud Drive I can copy folders on my desktop without any problems. The same problem is also documented here: https://discussions.apple.com/thread/253885938?page=2 **What I did:** - Booting in safe mode - PRAM Reset - Uncheck iCloud Drive couple of times - Killall Bird - Tried everything from this topic https://apple.stackexchange.com/questions/264915/icloud-drive-is-stuck-uploading-items-and-no-longer-syncs Nothing worked. **Just deleting the CloudDocs Folder helps for a couple of Minutes**. While it starts resyncing I can copy folders an everything is ok till it finished syncing. Then the problem is back. So what I can do? Would be great to get your help and expertise!
