Everything else seems to be working fine but the dishes are not drying.
From what I've read, it may either be the high-limit/temp thermostat or the heating element.

Are the high-limit thermostat and high-temp thermostat the same thing? Some sites seem to have the same item with different names.

How can I confirm which is the issue?

thanks.

I removed and tested the heating element as well as the hi-limit thermostat #661566

Both tested fine for continuity.

I also tested the thermostat by placing it on a griddle.. when it heated up to about 240 degrees, the circuit opened so it seems to be working as well.

What else could be the problem?

thanks

Here are your parts
Parts for Whirlpool DU920QWDQ3 Dishwasher - AppliancePartsPros.com

See the attachment for the tech sheet.

Using a meter check from P6 (White/Red) on the control board to White/Violet on the door switch.
If you measure the heater resistance ( about 25 ohms) then odds are that it is a control board problem.
