Be patient. That looks like my heirloom aloe. It's a very tough plant and does not require a lot of water anytime. It can take it weeks to begin and grow roots which is happening while the above soil portion of the plant just stays static or looks stressed more and more. That will reverse when the roots have generated enough to cause the rosette to begin growing. I go through the process every spring when I start them in a container outdoors. It can take a couple of months for visual active growth, but once it does begin there will be a lot of new growth, including offsets, in a short period of time. Just be careful with the water.
