Cannot access defaults field of Properties

[inadquatecoding]

Running Windows 11 with Java 1.8.0_301. I tried updating the XStream file myself but not sure of the directory, This simulator ran fine on another computer running Windows 10 though. The repo seems to be bundled with XStream 1.3.1 and the current version is 1.4.18.

Exception in thread "main" java.lang.ExceptionInInitializerError: Cannot access defaults field of Properties

I located the XSream jars in the directory .\Jad-Practice\lib\ but there are 2 files there and I replaced xstream-1.3.1,jar with 1.4.18 but the issues still occured.
