MMU2S not loading filament

Hello, about a year ago I upgraded my MK3 printer to an MK3S+MMU2. Despite some minor issues with clogging after repeated filament changes everything's been great. Recently, however, the idler assembly on the MMU2 has decided to stop working correctly and I am unable to load any filament. I have opened it up and nothing is jammed in the mechanism and everything appears to be fine mechanically. Upon powerup, the MMU goes through the standard startup calibrations and all motors appear to move easily and find their proper home position. Once I try to load filament the idler does not move to clamp the filament. It will move to the "ready" position hovering above the correct filament slot but does not rotate down to press the filament to the drive gears. This issue came out of nowhere and popped up immediately after finishing another print. I have since tried reflashing the latest firmware to the printer and MMU board with no success. If anyone has any ideas as to why it's doing this they would be greatly appreciated.
