[Geschlossen] Critical Error when opening ATE

Hi there,

I'm currently facing an issue regarding the ATE. After migrating the site to a new Domain, it started showing that there has been a critical error, when trying to update translations.

I already did the following:
-> Updated all Plugins to it's newest versions
-> Deactivated everything except Elementor / WPML Multilingual CMS
-> Went to Support -> Troubleshooting -> Synchronize local job ids withe ATE jobs + Set language information. After that I went ahead and deleted all open jobs from the translation management. Still didn't work.

I activated the debug log. Here is the informatione:
