according to the line this version of the Java Runtime only recognizes class file versions up to 52.0 you are running older version of java. to run komga u will Java version 17 or newer. read the following https://komga.org/docs/installation/jar

As mentioned in the previous comment, your Java is too old. You can check the version using java -version
