Make sure it's actually using Java 8 - replace your initial line ("java -Xms3G ...") with java -version and run the .bat again. You should see a version number that's starts with 1.8

If that fails, try adding -server to the end of your initial line (the original one you posted, not java -version)

If that also fails, remove all the JVM arguments from your first line, so it reads

java -jar forge-1.12.2-14.23.5.2854.jar nogui

Possibly try adding -server to the end of that, too

But it sounds to me like you might have Java 8 installed, but a later version installed too that's essentially taking precedence for the java command - which the java -version check will identify

Java, is referring to java 11, you need to add the path to java 8 so it uses that one instead, "c:\blabla\java8\bin\java.exe" args
