Lots of sites on X down - memory issue?

I have had 5 websites crash today. This message came from one of the site owners: (https://precisionorganic.com/)

I noticed that the PO website was showing a White Screen of Death error when I tried to visit it today. I also couldn’t login to the WP admin page. I went into the server Cpanel and, after a lot of mucking about updating plugins, updating php.ini settings, updating php version, etc., I found that the X-Child theme was causing a massive memory leak which then caused the server to shut the service down. I have changed the theme to one of the generic themes for now, but we might need to get some support from the X-Child developer as to why this happened and how we can prevent it happening again.

To help you here are the important parameters:

PHP version: 8.1.16
Wordpress version: 6.2
PHP memory_limit: 1024MB

I have re-enabled all plugins but before we can re-enable the X-Child theme we need to know how to stop the memory leak. I can always downgrade the PHP or Wordpress versions if the theme doesn’t support them, but the problem happened prior to me applying updates."

I also have problems with
www.cartoonkate.co.uk
www.frontrunnersinnovate.com
https://www.depthphysiotherapy-oxford.co.uk/
and I’m too scared to look at the others!

Looks like the first site in the list is back and on the patched version. Are you all good here now? Just going through the other sites now? See notes on WordPress 6.2 if you have not already and have a great weekend.
