You need a new bottom bracket.
You will need a crank arm puller and the correct BB tool for this
The size should be printed on the BB itself
Bottom bracket bearings are shot, you’ll have to pull the crank arms and replace the bottom bracket. It’s not difficult and the parts/tools are affordable https://youtu.be/6jhTG-bwy6E?si=JGa6JsOd6RlOOYQ5
