After I initially used the caulk shown in the attached photo I put a long screw into the top and wrapped the top with gorilla duct tape. I put it in the cabinet standing up right for many months. When I opened it up today to use it on something it was completely dried out. How do I prevent that? What’s the proper way of storing that silicone so it doesn’t happen?

Many months is your key...
Even unopened, some types of caulking can/do go bad... solidify.

professionally, I keep all sealant stocks rotated for usage... truck and shop.

I’ve used it previously to seal around outdoor lighting fixtures I’ve installed. Today was trying to use it to close the 3 or the 4 opening in a junction box as only one set of wires is coming up from another junction box and the load bundle was coming in through the back so I didn’t need the other bottom opening and don’t need either of the two openings on top.

What I have done to seal a tube is use some plastic wrap or a balloon and slide it down over the tip.
If air can't get to the contents it will stay usable for quite a while....some things longer than other.

As mentioned, it has a shelf life.

I use black electrical tape. A piece over the top and a few wraps around the stem.
Squeeze the caulk gun just hard enough to push out remaining air from the tape.
Sometimes it last for years in my basement.

FWIW...Don.

The key to keeping a used tube of caulk usable is to insert a piece of thick wire way down into the tube past the tip. I have a section of aluminum transmission wire I came across, the material is around 1/8" dia. Sealing the cartridge with a long piece allows un-hardened caulk a way to come out. Sealing with a screw of something short will eventually dry out and become useless.
