I have checked your debug information and here are some things that you need to attend to.
1. I have observed that the PHP limit for your "WP Memory Limit" is lower than the recommended 256MB or the required 128MB, as mentioned in the documentation found at: https://wpml.org/home/minimum-requirements/. To resolve this, I kindly request that you contact your hosting provider and request an increase in the PHP value for you.
2. Please update the WPML plugins to the latest version.
