Magento 2.4.2 Contact Us Page gives 502 Error

Question

I am using Claue theme magento 2.4.2 with custom page (default) provided by claue theme. Code i was using is given below:

{{block class="Magento\Contact\Block\ContactForm" name="contactForm" template="Magento_Contact::form.phtml"}} 

But whenever I open the page in browser I get 502 error and php-fpm user for magento exits. If i remove the template from the above code, then it works fine without any error. I am not sure what's causing the error.

But yes, before this error, what I did was installed module https://github.com/Mestrona/Mestrona_CategoryRedirect, but even though I have now removed it. I am still getting the error. I then deleted the directory root and restored the directory from previous backup, but its still the same.

I am not sure if some data was changed in the database. Any help?

EDIT:

I also removed the redis cache but its still the same.

5xx error is from server, you can read the var/log and var/report folders to get the error messages. This is much better for debugging than just the http status code.
