Unable to start Minecraft server

OS Name/Version: Windows 12

Product Name/Version: AMP v2.4.6.4 running Minecraft Java 1.20.1

Problem Description:
I am unable to start my Minecraft Java server when using Spigot. However, I am able to start it when using Official. When starting it with Spigot installed I get the console output:

joptsimple.UnrecognizedOptionException: o is not a recognized option
at joptsimple.OptionException.unrecognizedOption(OptionException.java:108) ~[jopt-simple-5.0.4.jar:?]

Any help with this issue would be amazing thank you!

Steps to reproduce:

  • Step 1: Open AMP
  • Step 2: Set the server type to Spigot
  • Step 3: Click start server

Actions taken to resolve so far:
Had Java SE 20 installed and it didn’t work so downgraded to Java SE 17.0.8 to see is that would help, it didn’t.

What Java version is selected in AMP?

As shown in the screenshot below the selected java version is ‘jdk-17 (Unrecognised)’. No idea what this is meant to be.
