That crash report doesn't seem to come from Forge. Have you installed the Forge server? Please don't dump crash reports directly in the forums. Share a link to them on paste.ee instead, as explained in the FAQ.

Please share more detailed steps on how to reproduce this and we'll look into fixing it. I tried putting a music disc in and it didn't loop.

Please read the FAQ before posting. Do not dump the log directly on the thread as it often triggers anti-spam measures, resulting in slow support. Arclight and other Forge forks aren't supported here. Contact Arclight for help with crashes with their software.

The mod dev plugin for intellij is unofficial. The forge templates it spits out are sadly often incomplete, outdated or broken. To start making a forge mod, we recommend using the latest MDK from the files site for the version of MC you want to mod. You extract that zip and open it in IntelliJ. 1.8.9 is extremely old. New IDEs won't work with it - you need a similarly old IDE. If you're modding 1.8.9 purely because you want legacy spam click combat, consider the SpammyCombat mod for modern MC and mod modern MC instead.

Oculus is broken. Check for updates for it or remove it

Thanks, seems to be an edge-case bug with the new launch system introduced in Forge 1.20.3+. A temporary workaround until we fix the issue is to add the following JVM arg: --add-exports jdk.naming.dns/com.sun.jndi.dns=java.naming
