For information i have use all of this :

Plugins:
FancyHolograms, AntiCreeper, ATopPlayers, CoreProtect, dynmap, Dynmap-GriefPrevention, Essentials, EssentialsChat, EssentialsSpawn, GriefPrevention, LoginSecurity, LuckPerms, Maintenance, SkinsRestorer, Vault

Using paper-1.21-109

You are using an outdated version of CoreProtect that does not support 1.21, v23 solves this issue.
To currently get v23, you must either be a Patron or you can compile the plugin manually through the GitHub for free.
