This is the error message I get:

I've tried updating, reinstalling, and downgrading my version of Java and it refuses to launch. This is what I've included in my .bat file:

@Echo off

call settings.bat

:start_server
echo Starting Sky Factory 4 Server...
java -server -Xms4G -Xmx12G -jar forge-1.12.2-14.23.5.2860.jar nogui
pause
exit /B

goto start_server


I do not get this problem when I run a vanilla server, I've looked around on github and other forums and usually reinstalling Java did the trick but it's not working for me. Thanks in advance.
