Unable to launch OptiFine 1.18

Version json: https://www.toptal.com/developers/hastebin/efedakeqes.json Note: I changed invalid OptiFine libraries’ links to valid ones from our custom server.

Options:

const otps: ILauncherOptions = {
  root: <root path>,
  version: {
    custom: "OptiFine 1.18"
  },
  authorization: getAuth(),
  memory: {
    min: "4G",
    max: "6G"
  }
};

const getAuth = async (): Promise<IUser> => {
 return {
   access_token: '',
   client_token: '',
   uuid: 'e63d3652-1822-4986-9e87-344f4d340878',
   name: 'H4kt',
   user_properties: undefined,
   meta: {
     type: 'msa',
     demo: false,
   }
 }
}

[H4kt]

Mojang launcher seems to have no issues when launching it

Hey H4kt, would you be able to join the Discord and shoot me a message? I’d like to collect more information so I can work on this issue.

If you don’t want to join the discord, my tag is Pierce#2657.
