A quick answer that comes to mind is "White Elephant". See Wikipedia [White Elephant][1] > A white elephant is a possession which its owner cannot dispose of and > whose cost, particularly that of maintenance, is out of proportion to > its usefulness. In modern usage, it is an object, building project, > scheme, business venture, facility, etc., considered expensive but > without use or value.[1] There is also a [party game][2] in which people set out to intentionally give each other white elephant gifts. One might also consider > Poisoned Chalice as suggested [here](https://forum.wordreference.com/threads/a-curse-in-disguise.1717550/), or from that same page: >A curse in disguise It's not standard or a set phrase, but it should be easily understood.
