I lost my ssh key, so I eventually decided to terminate the instance.
But now it has been stuck in "Terminating" stage for over 5 days.

stopping and restarting don't work.
Console connection also does not work.

In all cases (whether it console or CLI action) I get the error:
“instance *** is currently being modified, try again later”
Problem has persisted for over 5 days.
I can't create a new instance because the "Terminating" one is technically occupying resource limits.
I would like help killing the instance, please.
Thanks.
