Can be a problem with the plugin multiverse? or others? I'm running this

Modifyworld "1.19.7"
Multiverse-Core 2.5-b699
Multiverse-NetherPortals 2.5-b675
Multiverse-Portals 2.5-b725
PermissionsEx "1.23.3"
PlaceholderAPI 1.9.0.1
VariableTriggers 2
Vault 1.5.6-b49
WorldEditSelectionVisualizer 1.4.2

WorldGuard "6.1"

And, additional note, if I try to create the trigger in the yml file like world: 946,85,845: Cooldown: 1 Script: - '@player Ouch!' It doesen't work either
