This actually worked, thank you so much, any idea why it wouldn't just work with just java in the command line if 1.18, 1.19 and 1.15 servers just work?

Have java 8 update 333 64-bit installed.

getting this error 2022-06-23 10:38:19,322 main WARN Advanced terminal features are not available in this environment [10:38:19] [main/INFO] [cp.mo.mo.Launcher/MODLAUNCHER]: ModLauncher running: args [--gameDir, ., --launchTarget, fmlserver, --fml.forgeVersion, 36.2.35, --fml.mcpVersion, 20210115.111550, --fml.mcVersion, 1.16.5, --fml.forgeGroup, net.minecraftforge] [10:38:19] [main/INFO] [cp.mo.mo.Launcher/MODLAUNCHER]: ModLauncher 8.1.3+8.1.3+main-8.1.x.c94d18ec starting: java version 18.0.1.1 by Oracle Corporation Exception in thread "main" java.lang.IllegalAccessError: class cpw.mods.modlauncher.SecureJarHandler (in unnamed module @0x7fc2413d) cannot access class sun.security.util.ManifestEntryVerifier (in module java.base) because module java.base does not export sun.security.util to unnamed module @0x7fc2413d at cpw.mods.modlauncher.SecureJarHandler.lambda$static$1(SecureJarHandler.java:45) at cpw.mods.modlauncher.api.LamdbaExceptionUtils.uncheck(LamdbaExceptionUtils.java:95) at cpw.mods.modlauncher.SecureJarHandler.<clinit>(SecureJarHandler.java:45) at cpw.mods.modlauncher.Launcher.lambda$new$6(Launcher.java:55) at java.base/java.util.concurrent.ConcurrentHashMap.computeIfAbsent(ConcurrentHashMap.java:1708) at cpw.mods.modlauncher.api.TypesafeMap.computeIfAbsent(TypesafeMap.java:52) at cpw.mods.modlauncher.api.TypesafeMap.computeIfAbsent(TypesafeMap.java:47) at cpw.mods.modlauncher.Environment.computePropertyIfAbsent(Environment.java:62) at cpw.mods.modlauncher.Launcher.<init>(Launcher.java:55) at cpw.mods.modlauncher.Launcher.main(Launcher.java:66) at net.minecraftforge.server.ServerMain$Runner.runLauncher(ServerMain.java:49) at net.minecraftforge.server.ServerMain$Runner.access$100(ServerMain.java:46) at net.minecraftforge.server.ServerMain.main(ServerMain.java:43)
