Good afternoon!
I routinely use my set of display files (Github) for the 12864 display on my Duet Maestro, but recently the preheat page stopped working. When you open it the text is sometimes jumbled and it always freezes up the display. The easiest way to fix it is to simply reset the board. I did not edit the display code when the issue happened.
I have two different machines with the issue (both Maestros, one with 3.2-RC2 and another with 3.2.2). Another user just reported on Github that he's having the issue as well.
Below I've attached the code and also an M122 dump after it freezes. All other pages appear to work well.
Thanks for your help!

; Duet 12864 Menu Files
;
; This is a set of menu files for running a 12864 display with a duet3D control board.
;
; Written by Jadon Miller - 2/27/2019
; Partially adapted from the work of tinkerlifeprojects on Github.
;
; File "preheat"
;
; The goal of this menu is to make it easy to preheat the printer. It
; has a group of buttons to set the temperature and the current temperatures
; at the bottom with a shortcut to print/resume.
;
; Note: To modify the preset temperatures, there are two places to change for
; each temperature. The "T" parameter determines what is shown on the button
; and the number after the "S" is the temperature sent to the firmware. For example,
; if I wanted to change the second bed heater button to 45C, I would change this line:
;
; button C46 W19 T"40" A"M140 S40"
;
; To this line:
;
; button C46 W19 T"45" A"M140 S45"
;
; The hotend buttons work the same way.
;
; Note: you may need to change the gcode commands for each button if you don't use the
; default heater configuration.

This vibrated my BLTouch, causing inconsistent readings which is why I temporarily reverted to manual bed leveling.
