MMU2s All Lights Flashing

Whenever I try to load filament, all lights start flashing. Sometimes when this happens, the idler hardly rotates and same with the selector. I have inspected all connections on the M2 board. I have also tried: reseting the mmu2s, factory reseting the mmu2s, re-flashing the firmware on both the actual printer (mk3s+) and the MMU2s (I have the latest firmware, 3.12.1 and 1.0.6 on the mmu). In addition, I have tried plugging the mmu into an external power bank and making sure it's not in stealth mode. Any suggestions would be much appreciated!

I have:

   - Stock firmware (3.12.1, (1.0.6))

   - An MK3S+

   - A modded buffer

  - The black PSU

Thanks!

Yes, it's a long thread...
