The picture says "unable to access agent.jar". I think that means you need to download the agent.jar file into the directory where you are running the command which launches that agent.
I continue to believe that you may be making a more fundamental mistake than the command line arguments. If you want to run an agent, and that agent is a Linux agent (or FreeBSD or macOS or Solaris or Raspbian or ...), then my first preference is to use the "ssh based" technique to start the agent, instead of using the JNLP based technique to start the agent. If you want to run an agent and that agent is Windows, then you'll need to use the JNLP based method. In my small environments, I've preferred to configure Windows agents to launch themselves from a command line on the Windows agent computer, rather than trying to make the Jenkins master start the agent.
