Tips for people stalling from close guard?

Context I’m a smaller guy, and I play a lot of guard, but with one person in particular the just kneels from inside my closed guard. Hands elbows everything tight. They won’t attempt to pass the just sit there like a rock. When I attempt a sleeve or collar grip they try to wrap my lapel around my arm to trap it which i defend. But they generally keep everything so tight arms neck where I have no attacks. My only thought was just to open up my guard and go into passing but I thought that might be me being lazy.

Anyone run into this?
