Hi -
I have two Survey123 forms which I last published on December 1. I can confirm both forms were working well after being published. Today, I went in to the form and received an error:

There are two versions of my Survey123 form - one for data entry and one for data updates. They both reference the same hosted feature layer. Both forms show this error when I launch them. One form is embedded in Experience Builder and the other in a Dashboard. As a note, there is not field or domain of just "T" in the forms.
These forms and apps have not been touched since Dec. 1. Surveys were published via Connect version 3.16.106.
Can someone please advise of this problem?
Thank you,
