Documents & Desktop folders not readable via filesharing (folders visible, zero byte content within) - all other Home directory folders visible
I'm trying to figure out why I can't read my Documents nor my Desktop folder when I'm connected via filesharing to my Mac. Filesharing is turned on, and all other folders in the Home directory are accessible. I just upgraded to Catalina, but I'm not sure if this was happening before.
From another Mac or a PC, I can connect to my iMac (connecting using my username and password) and I can see all the directories in my home folder. I can open and browse all folders EXCEPT for the Documents and Desktop folders -- the folders themselves are visible but when I click into them, they show as zero items (when there's > 1 TB of stuff in Documents, and lots of files on the Desktop).
I confirmed my file permissions for those folders are correct (myusername = read/write) and for good measure I also went to the home folder and applied permissions to all enclosed items. Still no access to these 2 folders on any connected computer, other folders are OK.
I confirmed I have SHUT OFF iCloud Documents and Desktop. I even toggled it on and off again. No luck.
Is there something unique about the Documents and Desktop folders that prevent me from seeing them even if I'm logged into the Mac using my admin account username/password?
Edit: this also affects the Downloads directory in the same way, yet Dropbox and others are OK. Seems to be related to default Mac OS directories for some reason...
