hello and welcome to the forum,
rclone, when possible, uses spare files for local downloads, only for local downloads
i assume, that q: drive is a network drive, not local
if true, then as per the debug log, you have two choices.
use --local-no-sparse or --multi-thread-streams 0 to disable
i suggest to add --local-no-sparse
and as you have shown and as per the debug log,
rclone downloads the file, depsite that error message.
