In the RHEL-8 worker scale-up job, we're seeing the crio service couldn't be started as 

TASK [openshift_node : Restart the CRI-O service] ******************************
fatal: [ip-10-0-57-24.us-east-2.compute.internal]: FAILED! => {"changed": false, "msg": "Unable to start service crio: Job for crio.service failed because the control process exited with error code.\nSee \"systemctl status crio.service\" and \"journalctl -xe\" for details.\n"}

The system log shows
