I'm temporary fix this in my app by subclass django Widget and add template_name property
from django.contrib.postgres import forms as postgres_forms
class SplitArrayWidget(postgres_forms.SplitArrayWidget):
template_name = ''

What does your form look like? I can't reproduce a crash with a straightforward form like:
from django import forms
from django.contrib.postgres.forms import SplitArrayField
class Form(forms.ModelForm):
tags = SplitArrayField(base_field=forms.CharField(max_length=200), size=3)
