Code to default state/country and hide country no longer work

Since May 2020, I had used the code below in "Code Injection" to default the State and Country fields, and then hide the Country fields for all of the forms on my site.  But it seems that Squarespace had an update a few months ago that broke this.   I'd like to know what I can do (code changes) to get that functionality back.  Below is the code I used and source.

 <script>
     Y.on("domready", function(){
     Y.all('input[name="state"]').setAttribute("value", "GA");
     Y.all('input[name="country"]').setAttribute("value", "USA");  
     });
</script>
<style>
   .field.country {
      display: none;
   }
</style>

One of the forms on the site is here: https://fullyfurnishedministries.org/donate-furniture1

For these fields?
