Strange why this issue suddenly appears, without any new plugins has been installed.
With all plugins deactivated there is still something wrong. You are right, it is not a theme issue, the same with TwentyTwenty.
Notice: wp_enqueue_script was called incorrectly. Scripts and styles should not be registered or enqueued until the wp_enqueue_scripts, admin_enqueue_scripts, or login_enqueue_scripts hooks.
