I use aspen bedding sold at Petco. I have only used it throughout his life, and I change it about every one-two months

No substrate is going to cause that. I don't know why people insist it does. Even the dustiest substrate will only cause quick sneezing to clear the nostrils. If your snake doesn't also have a RI, that is.

Sounds like your corn snake has an advanced RI. His only chance is immediate vet care to get a prescription for antibiotics, usually Baytril suspension, orally for 7-14 days. In severe cases, an injection initially.

Improper temps / environment, combined with stress/lowered immunity is usually the cause. Specifically, usually too warm with a lack of temperature gradient.

Drafty, too cold, dampness, unsanitary conditions can also cause it. Rarely, it is caused by the snakes lowered immunity due to being gravid, high parasite load, age, etc. while fighting off an asymptomatic virus. This opens the door for normally harmless bacteria to invade the upper respiratory system. Without proper antibiotic therapy, it usually turns to pneumonia and then its fatal.

Regardless of anything else, I'm sure this is a RI and vet visit is needed promptly.
