Issue

when I turn on the server, it turns off immediately.
‘The Minecraft server stopped within 5 seconds of starting, this is not a fault with AMP - you should check your Minecraft servers log files to find out why it is unable to start.’ but there is nothing written in the logs except server start line:
[30Dec2023 20:06:03.296] [main/INFO] [cpw.mods.modlauncher.Launcher/MODLAUNCHER]: ModLauncher running: args [–gameDir, ., --launchTarget, fmlserver, --fml.forgeVersion, 36.2.34, --fml.mcpVersion, 20210115.111550, --fml.mcVersion, 1.16.5, --fml.forgeGroup, net.minecraftforge, nogui]

Ticket sent me here. In poping up window i got this: ’ Unable to start server.

The Minecraft server stopped within 5 seconds of starting, this is not a fault with AMP - you should check your Minecraft servers log files to find out why it is unable to start.’

I checked the console and there was this:
Exception in thread “main” java.lang.IllegalAccessError: class cpw.mods.modlauncher.SecureJarHandler (in unnamed module @0x4a684241) cannot access class sun.security.util.ManifestEntryVerifier (in module java.base) because module java.base does not export sun.security.util to unnamed module @0x4a684241
