I’m on Jetpack Premium, and I have most of their features on.
I have received a reply from my hosting provider:
“Thank you for writing back to us. First of all, we would like to take this opportunity to apologize for the inconvenience you have experienced thus far throughout this process.
I completely understand your concern regarding the Amp plugin compatibility. I have reviewed the case history and understand that website links ending with /?amp link is not working and showing Internal Server Error. I have reviewed the screenshots provided by you are those were very helpful. I have reviewed the Amp Validator and it is showing a script error.
It looks like a configuration issue with the Amp plugin and not from the server end.
Also, I have reviewed the error_log file and it is showing the following error:
PHP Warning: PHP Startup: Unable to load dynamic library ‘ixed.7.4.lin’ (tried: /opt/cpanel/ea-php73/root/usr/lib64/php/modules/ixed.7.4.lin (/opt/cpanel/ea-php73/root/usr/lib64/php/modules/ixed.7.4.lin: cannot open shared object file: No such file or directory), /opt/cpanel/ea-php73/root/usr/lib64/php/modules/ixed.7.4.lin.so (/opt/cpanel/ea-php73/root/usr/lib64/php/modules/ixed.7.4.lin.so: cannot open shared object file: No such file or directory)) in Unknown on line 0
It looks like the Amp plugin is not compatible with the higher PHP version. Also, I have referred below help articles:

I have flushed the permalinks via WordPress Dashboard >> Settings > Permalinks and re-save. However, the issue was not resolved. Also, checked the .htaccess file located in domain directory /public_html/lifeofaworkingadult/ and there is no issues with that file.
It does look like there are multiple reasons for this issue to occur with the Amp plugin. We did try some of the fixes that do not require code changes. To prevent any further issues involving the site, we strongly recommend reaching out to Amp plugin support for more information on how to address this:

The issue you are seeing on your website is not caused by any wrong server configurations. It seems like a website plugin/design/coding issue. It is advisable to contact the web developer to get this checked.
As scripting/coding is something beyond scope of our support, we would request you to contact the plugin provider or developer to check on this and let us know if they would need us to make any changes from our end towards resolution, we’ll be more than happy to check it for you.”
