Hi Aneel,
you have two Java-Installations in your path, JDK 11 and JDK 21.
Only the first one, JDK 11, will be used when invoking java without specifying concrete pathes.
Additionally, can you check what Oracle/Java/javapath is pointing to?
Is it another java installation?
Can you check the eclipse log from your ServiceDesigner installation for detailed error messages when the popup shown in your first screenshot is shown?
Regards,
Holger
