if you want to keep playing the game, its sort of your problem unless they fix it.
Warzone sounds like it has a memory leak as short search shows adding more ram isn't answer, it just postpones when the problems occur -

My PC's memory usage in process of dropping the size of page file and how much is cached as up until last week I was playing a game that was using more space than I have. Wouldn't think 32gb isn't enough but if the game has a memory leak, it will keep taking memory until you run out. Only real way to fix that is to close game and load it again.
