I cannot allocate more ram

I'm attempting to make a 1.20.1-47.4.0 forge server but when I change the user_jvm_args.txt it does nothing so i tried adding it to the run.bat which it picks up on the startup console but then gives me this

I have uninstalled and reinstalled all my versions of java and tried deleting and restarting everything several times to no avail. I have no more ideas and would appreciate any assistance.

joptsimple.UnrecognizedOptionException: X is not a recognized option

JVM-Arguments begin with a -

So use -Xmx6G instead of Xmx6G etc
