It seems likely that you have multiple versions of OpenJDK installed. According to the Java Version Almanac, Class File Version 61.0 is available since Java 17. And according to Differences between Oracle JDK and OpenJDK:
Oracle JDK and OpenJDK builds are essentially identical from Java 11 onward.
Thus, OpenJDK >= 17 will be compatible with the freerouting builds available (at least as far as meeting the Class File Version requirement).
The "Java Runtime only recognizes class file versions up to 52.0" error indicates that you are using Java 8. Possibly openjdk8u?
Since you have openjdk21 installed, you should verify that it is being used. All of the typical troubleshooting suggestions apply: environment, class path, etc. /usr/bin/java --version should print something about OpenJDK 21.
Caveat: I am not familiar with Java, and all of the alternative runtimes and development kits are unnecessarily convoluted and confusing.
