There is an issue with my pro crisp! 

I love this device, I use it every day. Last night I was pressure cooking a few pototoes but after cooking was done, the cooker failed to unlatch. It is the next morning, there is no more steam to release but it is still trying to relieve pressure. I believe there may be some debris I missed cleaning that is blocking something (Powdered sugar- I air-fried some pastries and it went everywhere if that matters). 

Is there a way to manually unlock my pro crisp? Does anyone know? Please help!
