Failed to launch Minecraft 1.18.1 Server

I don’t know how the question is, but cmd gave me these:

Error: A JNI error has occurred, please check your installation and try again Exception in thread “main” java.lang.SecurityException: Invalid signature file digest for Manifest main attributes at java.base/sun.security.util.SignatureFileVerifier.processImpl(SignatureFileVerifier.java:340) at java.base/sun.security.util.SignatureFileVerifier.process(SignatureFileVerifier.java:282) at java.base/java.util.jar.JarVerifier.processEntry(JarVerifier.java:321) at java.base/java.util.jar.JarVerifier.update(JarVerifier.java:234) at java.base/java.util.jar.JarFile.initializeVerifier(JarFile.java:762) at java.base/java.util.jar.JarFile.ensureInitialization(JarFile.java:1033) at java.base/java.util.jar.JavaUtilJarAccessImpl.ensureInitialization(JavaUtilJarAccessImpl.java:72) at java.base/jdk.internal.loader.URLClassPath$JarLoader$2.getManifest(URLClassPath.java:883) at java.base/jdk.internal.loader.BuiltinClassLoader.defineClass(BuiltinClassLoader.java:848) at java.base/jdk.internal.loader.BuiltinClassLoader.findClassOnClassPathOrNull(BuiltinClassLoader.java:760) at java.base/jdk.internal.loader.BuiltinClassLoader.loadClassOrNull(BuiltinClassLoader.java:681) at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:639) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:188) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:520) at java.base/java.lang.Class.forName0(Native Method) at java.base/java.lang.Class.forName(Class.java:467) at java.base/sun.launcher.LauncherHelper.loadMainClass(LauncherHelper.java:780) at java.base/sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:675)

I deleted the FABRIC1.SF and FABRIC1.RSA in fabric-server-launch.jar\META-INF, then it can run properly for a while. And it shows this to me:

I changed Eula.txt, and it can work properly.

Tips: I run the server in the dictionary D:\000

No. The latest installer can download the proper Fabric (without FABRIC1.SF and FABRIC1.RSA) Thank you very much. : )

The eula.txt part is normal for minecraft servers.

The first error about the signature says the jar file has been modified in someway from the version built by fabric. Make sure you use the version provided by fabric. Using modified versions from somewhere else could for example mean you are using something infected with a virus.
