Running without GriefPrevention

• I attempted running the server without GriefPrevention installed.
• The problem does not occur when GriefPrevention is removed from the server.

Running with only GriefPrevention

• I attempted running only GriefPrevention on the server.
• The issue still occurs when GriefPrevention is the only plugin running.

Running on a fresh, clean server installation

• I attempted testing for the issue on a new server.
• The issue still occurs on a new server.

Using unmodified client

• I attempted testing for the issue with the vanilla client.
• The issue still occurs when using the vanilla client.

We appreciate you taking the time to fill out a bug report!

• I searched for similar issues before submitting this bug report.

What do you mean by "server doesn't open," the server doesn't start? If that's the case, we need startup logs.

1.18 is a Minecraft version. It is not a version of a server implementing the Bukkit API. Copy the output of /version.
"last version" is not a valid GP version.
