I have a few webforms on my D9 site. They all work for anonymous site visitors except for the contact form, which gives an "access denied" error.
The permissions under the form's Settings->Access tab are the same as for other forms that do work.
The form's access permissions are set to allow anonymous / authenticated / admin users to create and view/ update own submissions:
I did search for the solution but what I found didn't help. I tried the debugging code from https://drupal.stackexchange.com/a/315766 and get the following messages:
The website encountered an unexpected error. Please try again later.

I don't know what this all means. Where do I go from here? Thank you.
