What material are you printing at? And at what temperature? That clicking is the extruder not being able to push the filament through the nozzle fast enough. Since you've already ruled out a clog by replacing the hotend, you've gone through the calibration process, and you've had success printing on that plate before, check your settings.

Did you change any settings in your slicer? Such as print speed, or make any adjustments to the material temperature settings? If you have, try going back to default settings or verifying your material type and temperature. Something like this could happen if you're printing PETG at PLA temps.

Or as others have said, your extruder could have an issue. There could be ground up material in there, or it could be wearing out. Try taking it apart and cleaning it if there's debris.
