ATE Server Communication 401 Error - Specific to "Teams" Custom Post Type

This thread is resolved. Here is a description of the problem and solution.

Problem:
If you're experiencing an issue where clicking 'Edit in Advanced Translation Editor' on a 'teams' post type redirects you to a blank page, and your logs show an 'ATE Server Communication Unauthorized "status":401', this indicates an authentication problem between your site and the ATE server.
Solution:
First, ensure that you have cleared the cache of all caching plugins and performed the following actions:
1. Clear WPML cache
2. Synchronize local job ids with ATE
3. Synchronize local job ids with ATE jobs
4. Synchronize posts taxonomies
5. Fix post type assignment for translations
If the issue persists, we recommend updating WPML to the latest version to ensure compatibility and functionality. If this solution does not resolve the issue or seems irrelevant due to being outdated or not applicable to your case, please check related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins. If problems continue, we highly recommend opening a new support ticket with us for further assistance.

jeffreyW-11	Hello, We are experiencing an issue with the Advanced Translation Editor on one specific CPT ("teams") only. For all other post types, ATE works correctly. When clicking “Edit in Advanced Translation Editor” on a teams post, we are redirected to a completely blank page. In the logs, we consistently see the following error: ATE Server Communication Unauthorized "status":401 So it seems to be an authentication issue between our site and the ATE server. What we have already tried We cleared the cache of all caching plugins. We also ran the following actions in: Clear WPML cache Synchronize local job ids with ATE Synchronize local job ids with ATE jobs Synchronize posts taxonomies Fix post type assignment for translations Despite these actions, the issue persists only for this CPT. Additional information Other CPTs work fine with ATE The problem is reproducible on every teams post The page loads blank immediately after clicking “Edit in Advanced Translation Editor” Error log consistently shows 401 Unauthorized related to ATE server communication
