New MacBook Air 2019 freezing

Hi guys,

Just recently bought a new MacBook Air 2019 and it freezes semi-regularly.. not sure if this is normal or indicative of something more sinister. I don't have a lot of apps/docs etc. taking up space and it happens if I have only safari open with ~3 tabs open. I use command control esc to close programmes but just worried it might mean that there's something wrong with the Mac itself!

I might be just paranoid, saved a while to buy this and want to make sure it isn't faulty! ahaha
