Cactus turned to mush overnight

This guy was upright and not very yellow at all last night. This morning, he looked like this. Is there anything I can do? It happened so fast. I’m sad because it was given to me by a family member.

Live in South Florida, I’ve been keeping it sheltered so it doesn’t get a lot of moisture.
