Cron reschedule event error for hook: {"schedule":"litespeed_filter","args":[],"interval":60}

Hello Sir,

Please help me to resolve this issue while I use Lightspeed with RankMath, my Rankmath plugin shows this error -

Cron reschedule event error for hook: litespeed_task_ccss, Error code: invalid_schedule, Error message: Event schedule does not exist., Data: {"schedule":"litespeed_filter","args":[],"interval":60}

Due to this, my new posts take too much time to index, and my website ranking also drops.
