I’ve got an Ender 3 pro v2 motherboard (not silent steppers) that you can have for shipping costs if you determine that’s the issue. If you do, pn me your zip code and I’ll let you know how much it would be.

I would test the ribbon cable to the extruder before replacing the mobo. That’s a more common failure. Plug one of the other stepper cables into the extruder port and see if it moves. If it does, the mobo is good and the cable Is bad.
