New York strip roast came out like beef jerky
You made 2 mistakes.


A pressure cooker (like InstaPot) relies on water to make steam to create pressure.  You should not put a roast in the pressure cooker without adding liquid.
A pressure cooker is ideal for breaking down collagen in cheap, tough cuts of meat to make them tender.  NY Strip is a premium cut that is already tender - just roast it in the oven.
