Hello Everyone! I created a Minecraft Forge Server the other day, had no issues running it. (version 1.16.5) (vanilla) I updated my Java today, because I had a prompt on my desktop to update and I did. Now when I run the Bat file I get a sting of errors I am not too sure how to combat. I have read that Minecraft Forge only runs on certain versions of Java and I cannot find a source to resolve or change my Java version. Below is the string of errors in the cmd. Thank you for taking the time to read this!
