Running the Forminator plugin (hidden link) seems to conflict with Toolset Access. This happened today, and has been working for over a year before -- I'm assuming either a Toolset, Access, or Forminator auto-update. Disabling either Access or Forminator fixes the problem.
This is a staging duplicate site of the production site where this issue occurred.
PHP error message:

Commenting out lines 208-211 in types-access/application/controllers/permissions_post_types.php fixes the error. It seems the 'Toolset_Post_Type_Exclude_List' class is for some reason not available to the Forminator plugin.
Here is the commented-out code:
// if ( empty( $this->excluded_post_types ) ) {
// $post_type_exclude_list_object = new \Toolset_Post_Type_Exclude_List();
// $this->excluded_post_types = $post_type_exclude_list_object->get();
// }
