Pull out lint catcher screen not catching lint ,yet exhaust vent blowing strong

greetings earthlings-my dryer pullout lint catcher screen used to have a fresh batch with every load,but all of a sudden,there’s no lint,hardly any,and so i went out to the backyard where the exhaust vent is ,and the blast of warm air is very strong… anybody have any clues as to what is screwed up? please give input,thanks , zeus008

A model number may help others help you.

You may have an internal seal inside the unit that has blown and the lint is now being blown into the unit.
