I managed to solve the java problem by deleting all the versions and using a "jarfix" file to solve the interferences. But definitely the optifine was the problem. Thank you so much !, I had 3 days with this, u save me.

I already tried it, it doesn't work

Hi everyone !, I have a minecraft 1.18.2 server with 15 mods. A couple of days ago I updated to Windows 11, and I have had this recurring error, I have tried to reinstall the forge server with all versions of java JDK (17, 18 and 19)(also i try to start the old server with the same java versions but nothing happens). But with none of the three I have been able to overcome this error, I appreciate any help or idea to solve it!, thanks! (The server runs smoothly when I don't include the mods) D:\User\Desktop\Server>REM Forge requires a configured set of both JVM and program arguments.
