everything seems fine except line 11

import { GuildMember } from "discord.js";

export function getPermissionRank(member: GuildMember): Number{
    if(!(member instanceof GuildMember)) throw new Error('Argument 1 is not supported. (supported: GuildMember)');

    // the above code may be causing this issue, the rest i know is fine

<Interaction>.member may not be a GuildMember if the interaction was received in a dm or from a guild that isn't cached you'd want to typeguard with <Interaction>.inCachedGuild() if this is done prior to execute being called, then you'd want to specify the generic <"cached"> for your interaction's type as a side note, CommandInteraction is for all application command interactions, including context menu commands ChatInputCommandInteraction is for slash commands if you're typeguarding the interaction somewhere before execute is called, you can use the <Interaction>.isChatInputCommand() typeguard

i used .isChatInputCommand() in my event handler

then that's perfectly ok I just wanted to mention since you typed inter as CommandInteraction
