Spinning wheel - turning on

Hi. I just like to ask, everytime im turning on my MacBook Air 2019, there's a colourful spinning wheel showing up. I can't use my laptop for like 3-5 mins and if I do, it will automatically shut down or the screen is frozen. I don't know what's going on. It wasn't like this before. Is there anything that I need to do? The OS is the newest one. Thanks
