On a new clutch, slip happens because the bearing doesn’t become fully disengaged and keeps pressure on the cover so reducing the clamping force on the friction disc, if you have free play (try and move the arm forwards and backwards it should move by a few mm)when the clutch is in its normal "rest state", i.e. foot off, pedal up, and the cover is applying the most clamping force, then it’s not the bearing, carrier or the arm as they are effectively disconnected and dormant therefore not influencing the disc and cover.
Clearly something else is going on here
