Love2d Player Movement

I am trying to make a simple player controller where when i press shift the player moves towards the cursor
It works but i don't know how to fix the jitter it does

The code is in 2 files:
main.lua

require("player")

function love.load()
    player = Player.new(0, 0)
    player.speed = 100
    mouseX, mouseY = love.mouse.getPosition();
end

function love.update(dt)
    mouseX, mouseY = love.mouse.getPosition();
    local key_up = love.keyboard.isDown("lshift")
    local key_space = love.keyboard.isDown("space")
    
    if key_up then
        Player:move(dt, {["x"] = mouseX, ["y"] = mouseY})
    end
end

function love.draw()
    love.graphics.rectangle("fill", player.x, player.y, 5, 5)
end

player.lua

Player = {}
Player.setmetatable = Player

function Player.new(x, y, speed, stop_radius)
    Player.x = x
    Player.y = y
    Player.speed = speed or 100
    -- Player.dash_speed = dash_speed or 100
    Player.stop_radius = 20
    return Player
end

function Player:move(dt, cursor)
    -- Check whether the player is at the stop radius or not
    dx = cursor.x - player.x
    dy = cursor.y - player.y

    distance = math.sqrt(dx^2 + dy^2)
    
    -- Only move if the player is outside the stop radius
    if distance >= Player.stop_radius then
        local angle = math.atan2(dy, dx)
        local angle = angle * (180/math.pi)
        Player.x = Player.speed * math.cos(angle) * dt + Player.x
        Player.y = Player.speed * math.sin(angle) * dt + Player.y
    end
end

return Player

Ong idk how to fix ts
