I’m by no means an expert on indoor plants. But from what little I can see, I’d suggest repotting it into a slightly bigger pot with excellent drainage. Aloe is typically an easy plant to maintain. If you pot it with water catching plate attached to it, the plant will thrive taking water when needed instead of you flooding the roots and causing them to rot. Which is what it looks like from that picture. It will fix itself in the right conditions.
Good luck
