Those seem unrelated, so more information will produce better advice.
When the high voltage power supply fails, the symptoms will look a lot like a bad tube.
If the 48 V power supply is bad, that will certainly affect the motors and maybe the controller, although Ruida controllers prefer a 24 V power supply with a 36 V upper limit.
They’re reasonably cheap & readily available:
Because OEM supplies are typically under-powered for the actual load, round upward to the next higher multiple of 10 A when you get one.
