Not sure what you need to see here Chris but this is a start...

i am not exactly sure what is causing this error but if i turn off the panel button use action list it does not error!
so some where in the action list i get this error and it i think it is the character animate play custom PressButton issue

if i get rid of the character animate action tinpot does not animate obviously but no error so the error exists in the play custom PressButton animation

As shown in screenshot i am using AC V1.70.4 & Unity 2019 2.21f1
Screenshots are as follows...
