Hello,

 

When starting the java file, the server crashed. Java version (build 1.8.0_251-b08)

Any idea?

Thank you

well this error occurs but the server is still running.

How are you starting the server? Looks like you are passing invalid commandline arguments to it.

Just double click on the .jar (forge-1.15.2-31.1.74.jar)

I tried with .bat and some options but same results
