Many years ago I had very similar symptoms, on two different cars. On one, turned out that the pressure plate diaphragm spring had distorted, and the clutch, therefore, wouldn't fully disengage. On another car, stored for a long time, the splines supporting the clutch disk rusted so the disk didn't move fully away from the flywheel when released.
