It's the right decision lol!
Perhaps a lack of watering during the dry period and the squash caught up during the rainy period. The skin has cracked because of this too rapid growth.
This is what happened to my plum tree, where it was necessary to eat the fruits quickly, because torn skin they do not keep.
The tear is too far apart for the squash to heal, moreover, since there is no more sap arriving, it can no longer do so.
Bacteria and yeasts must have started their meal and multiplied.
Lately I've had zucchini that must have been punctured by worms in contact with the ground. Like you, a kind of Latin comes out of the holes. I did not take care of it immediately, so I had to throw it in the compost due to accelerated rot.
