The best course of action from here will be to take a few leaf cuttings for propagation, then try and repot the main plant. The main plant will likely die before it regains enough roots to continue on, but there is a chance that one of its leaves will also root while still attached. This will leave you with multiple plants forming from the same spot, while your few leaf cuttings will be a backup in case the rooting fails.
