502 after Wordpress 6.1 release

[GreenLondon]

Since I updated WordPress to 6.1 several sites throw a 502 error. Is anyone else facing this?

Other sites have been updated to 6.1 but they don't have any issues at all.

I can't figure out what it is other than this message in my error log

WARNING: [pool www] child 122875 exited on signal 11 (SIGSEGV - core dumped) after 0.921735 seconds from start
[03-Nov-2022 09:01:35] NOTICE: [pool www] child 122876 started

I did the following:

1. Disabled the plugins
2. Activated the 2022 theme
3. Updated WP to 6.1 and immediately the site had 502 error
4. Restored to WP 6.0.3 and everything is ok.
