[Unable to launch forge-xx-universal.jar, log+cmd error+java versions included]

Hello guys,

I'm trying to run a Minecraft Forge server, but I can't launch the file forge-1.12.2-14.23.4.2705-universal.jar. It doesn't even show anything. 

I found something in a log and down below there is an error from launching via cmd
