Comment (by AndyHenderson):

 FWIW, I've just seen this error in our log:


 {{{
 [01-Feb-2023 19:17:22 UTC] Cron unschedule event error for hook:
 backwpup_cron, Error code: could_not_set, Error message: The cron event
 list could not be saved., Data:
 {"schedule":false,"args":{"arg":"restart"}}
 }}}

 We implemented 6.1.1 shortly after release but have not seen the error
 until now. OTOH, we implemented PHP 8.1 from 7.4 yesterday. Coincidence? I
 hope I'm not setting a hare running.

 Andy
