May 31 09:44:12.048 CRIT Failed to start beacon node             reason: Syncing from genesis is insecure and incompatible with data availability checks. You should instead perform a checkpoint sync from a trusted node using the --checkpoint-sync-url option. For a list of public endpoints, see: https://eth-clients.github.io/checkpoint-sync-endpoints/ Alternatively, use --allow-insecure-genesis-sync if the risks are understood.
