LCD Knob not working after Firmware update

I just flashed my MK3/MMU2s today with the latest firmware.

After a successful update to 3.11.0.4955, the encoder knob quit responding. No beep.. nothing.

I checked both cables (including continuity checks) and they were fine. Solid connections too.

I reinstalled the prior firmware that was known to work (3.10.0.4481)

At this point, the knob still isn't working, but I get a beep when I press it.

 

Any ideas?

So, long story short.... I ended flashing the printer with 3.9.0, which worked. Then found out that the mmu and filament sensor cables were swapped.

After the cables were fixed, I reflashed 3.11, and everything was back to working
