I would say it's a faulty timer. Not the timer motor but timer contacts. Unplug dryer, set timer into air fluff cycle. Check for continuity between timer terminals T and F or T and X. If no continuity between either, then timer won't advance and timer is faulty. This dryer has one of those cheap timers that are always failing. BTW, this dryer does not have any moisture sensor.
First try resetting washer motor/inverter control. Unplug washer for 1 minute. Plug back in and then open/close lid 6 times within 12 seconds. Just lift lid a couple inches, enough to operate the lid switch. If still the same problem, get the tech sheet from inside the control panel. Place washer in service manual as per tech sheet and select spin test mode. Check DC voltages at control board 5 pin plug. Use violet wire for common. Violet to black and violet to blue should be 12vdc. Violet to yellow and violet to red should be 0vdc. If correct, then faulty motor/inverter. If your getting 12vdc on either yellow or red wire, then faulty control board.
Remove the pulley and clutch from the motor. Could be that the roll pin has sheared off. Roll pin goes through motor shaft and drives the clutch. Clutch drives the pulley. Check thickness of clutch pads. If good and roll pin is good, may just need a good cleaning and lubrication of interface between clutch shoes and clutch assembly.
