Define "release". Do you mean taking your foot off the clutch pedal and letting the transmission gears spin? If so that's "engaging" the clutch, not releasing it. It sounds like you've got bearing problems inside the transmission, since the throwout bearing won't be turning when there's free pedal at the top of the travel.
