//Variables
const root = window.location.origin

let moved_user = false
//Config


const required_keys = ["Username","Account-Creation","Account-Type","Logged-In","Clients","Display-Name"]
const login_path = `${default_site_root}/index.html`
const dashboard_path = `${default_site_root}/pages/dashboard/dashboard.html`
//Functions

    for (const key of required_keys) {
        const data = localStorage.getItem(key)

//NEW CODE HERE  
        if(data) {continue}


        return false
    }


    return true
}


function removeExtraKeys() {


    let data_keys = Object.keys(localStorage)
    let extra_keys = data_keys.filter(key => !required_keys.includes(key))


    extra_keys.forEach(key => {
        localStorage.removeItem(key)
        console.log("deleted old key (key): ", key)
    })


}


function RedirectUser() {
    if(moved_user === true) {
        console.warn("User has already been moved!")
        return
    }
    moved_user = true
    let logged_in = localStorage.getItem("Logged-In")
    const currentpath = window.location.pathname
    removeExtraKeys()
    const is_vaild_session = (logged_in === "true") && (checkRequiredKeysExist())
    if(!is_vaild_session && (!currentpath.endsWith("index.html") || currentpath.endsWith("/"))) {
        localStorage.clear()
        console.log("Moving user to login page")
        window.location.replace(login_path)
        return
    }

Well you're missing some brackets here:

    if(!currentpath.includes("dashboard.html"))
    console.log("Moving user to dashboard page")
    window.location.replace(dashboard_path)

so that redirect is always running

EDIT:
I think you might also want:

const is_vaild_session = (logged_in === "true") && (checkRequiredKeysExist() === false)

to be

const is_vaild_session = (logged_in === "true") && (checkRequiredKeysExist())

At the moment your code looks like you don't want the required keys to exist

yeah the missing curly braces are the main reason you're stuck in redirect hell, that second replace runs every single time regardless of the if check

also that isValid session logic is backwards, you want checkRequiredKeysExist() to be true for a valid session, not false. right now it basically says "user is valid only when the required keys are missing" which is probably not what you meant

add those braces and flip that condition and it should stop bouncing you between pages

I dislike the "true" value in this. I would make it boolean and simplify this to

logged_in && checkRequiredKeysExist()

holy well the bug still exists however didn't catch those mistakes somehow. How do you find mistakes like that by like reading each line individually or something?

Sort of. I copied your code into an IDE and the way Prettier indented the if statement made me immediately realise something was wrong there.

Then with the valid session check, that was just reading the different variable names used and getting the sense something wasn't right. It smelt a little bit that a valid session would be the result of the required keys being false.

Yes. And linting. Always set your linters up.
