critical website error | WordPress.org

When downloading and installing the free version, configuring all my required credentials, when configuring the templates, a critical error appeared on the site after saving, however, this error only prevents you from viewing the template tab, the rest of the site is ok… and even after removing and reinstalling the error continues. All the configuration was done following official videos of the application on YouTube. And the API is ok and active and working, when I test it from the META business panel it works fine.
