auto-update for Wordfence set to off
“disable config caching” checked on options page
htacess rule in place from here:
https://support.wordfence.com/solution/articles/1000129050-running-wordfence-under-litespeed-web-server-and-preventing-process-killing-or
That fixed it for another user. Can you try and confirm for me?
Thaks!
