I assume you have iCloud enabled. If so, these three folders are ’special’. Try logging out of iCloud & rebooting and see if the problem persists.
I would also recommend filing a bug with Apple and include a sysdiagnose taken while the problem was reproducing (sudo sysdiagnose). Or at least a spindump (sudo spindump) while the problem is reproducing. —Rob > On Apr 19, 2020, at 9:54 AM, David M.
