We are seeing this behaviour even with mounted disk images. We will test with AFP server also.
We are not seeing this behaviour when we copy using cp or mv terminal commands or any other application. Its certainly due to some changes in DesktopServicesHelper on macOS Tahoe which triggers file deletion if its takes more than 5 seconds to transfer.
We have tried with less than 5 seconds like 4.5 sec or 4.9 seconds and it works as expected.
