I recently converted a .jar file containing a java project into a .exe file using Launch4j, however, I am unable to launch it by clicking the icon or by right clicking and selecting run. I am able to run it through the console but I intend to publish it. Can someone help?

My jdk version is 21. I am using an Ubuntu system.

.xml configuration:

<launch4jConfig>
<dontWrapJar>false</dontWrapJar>

<jar>/home/james/Desktop/waw.jar</jar>
<outfile>/home/james/Desktop/Wild_And_Wyrd/waw.exe</outfile>
