It also seems to be related to this topic, that also handles an issue around file attributes/security on files.

Windows 10/11 file copy system? Version issue? Bug? Conflicting combination with current version FFS?

FYI:
I'm, also having this issue copying files from NTFS (Windows 10 and 11) to FAT32 NAS or EXT2/3 NAS.
With admin rights using version 12.2.
The rights of the destination need to be applied to the copied files.

Tools - Options
Turn off: Copy DACL, SACL, OWNER, GROUP while still logged in with Admin rights did continue the sync.
Before this option was never needed, and now new to me.

Just upgraded to Version 12.2, and now noticed also the same behaviour.
It works perfect on Windows 10.
With exactly the same hardware it gives following errors:

ERROR_PRIVILEGE_NOT_HELD: Een van de vereiste bevoegdheden is niet aan de client toegekend. [GetFileSecurity]
