I just did a quick test and it seemed to work as I expected:
tag[task] - lists all tasks
!field:status[done] - filters that list down to only open tasks
tags[] - lists all the tags of those open tasks
tag[projects] - identifies which of those tags represent projects
That should give you all projects that have open tasks. Maybe there is a
capitalization error, e.g. "done" vs "Done"?
