 However in all instances that we have seen this issue, it was with PHP 7.4
 so @AndyHenderson I don't think that your PHP update to v8.1 was relevant.

 saying the fix is to update PHP? Is there any code changes for this coming
 up in the next version of wordpress?
 We're currently running WordPres 6.1.1 and we updated to PHP 8.1 a little
 over a month ago and I'm still seeing errors like this in the logs about
 once a month (some of these are from plugins like Wordfence it seems):

 {{{
 [17-Feb-2023 15:24:47 UTC] Cron reschedule event error for hook:
 action_scheduler_run_queue, Error code: could_not_set, Error message: The
 cron event list could not be saved., Data:
 {"schedule":"every_minute","args":["WP Cron"],"interval":60}
 [08-Feb-2023 21:36:00 UTC] Cron reschedule event error for hook:
 wf_scan_monitor, Error code: could_not_set, Error message: The cron event
 list could not be saved., Data:
 {"schedule":"wf_scan_monitor_interval","args":[],"interval":60}
 }}}
 So I can confirm that updating to PHP 8.1 will not resolve this issue.

 Furthermore, I don't think that WordPress is officially ready for PHP 8.1
 yet as our logs are filled with errors from the "wp-includes" folder in
 WordPress.
