You can't change the parent. You need to recreate the subtask under the correct parent and close (resolve) the old one with a reason like created in error
Try with the information in this post, but your error is strange

@Vero Rivas Thank you for your reply!
The link you have mentioned above does not tell about how to change the parent of a subtask.
Earlier I could do that easily.
I have observed this strange error recently. :(
