pasting in the jvm arguments results in this error on java 19/17

Using no jvm arugments results in this error: (java 17 and 19)

Upon looking around I needed to update mmc-pack.json but this still results in this error:
https://paste.ee/p/6mHQZ

It seems you copied some sort of special non-breaking space/newline characters from the browser so java didn't split the arguments properly, try copying from a different browser or via another program such as notepad (copy in browser, paste in notepad, copy in notepad, paste in mmc)

oh, or alternatively put a space after every line, maybe java on windows doesn't split arguments with newlines from mmc

Thanks this worked however even with these arguments working for some reason I still get this error:

Be sure to read the directions on installation here https://github.com/GTNewHorizons/lwjgl3ify -- multimc needs a small bit of effort to make it work

Thanks yep I just needed to move the extracted patches folder to the modpack folder it all works fine now 🙏
Might as well ask here I guess but is there a way to make it work on the default minecraft launcher or only the 2 supported ones

Theoretically you can make it work on the vanilla launcher by adding some json metadata files like in multimc, but I haven't written them in the vanilla format
