Hi, I'm also having trouble starting Wandora.

Java version 18 is running on Windows 11 64-bit. The process is stuck here.
I have attached the cmd image
It is stuck here

Hello Shreyashtijare

It looks like Java's Nashorn Javascript engine is deprecated and has been removed from JDK 15 (and later). It has been replaced by GraalVM:

https://www.graalvm.org/22.1/reference- ... tionGuide/

Wandora initializes some predefined scripts written in conf/options.xml with Nashorn Javascript engine. Just look in the options.xml file and search Nashorn. I have not tried to fix this yet but expect the problem disappear if you replace the 'Nashorn' with GraalVM's script engine name 'graal.js'. Also, version number should be changed. I have not investigated if the new graal.js is compatible with Nashorn and can run predefined scripts without errors.

Kind Regards,
