2020 MacAir Running Slow + Crashing

Hi guys,

My Mac is running slow and crashing more often than I would like it to. I mainly use it for work, study, watching movies etc. So nothing too straining, in theory. I blamed the issue on its age but I ran an EtreCheck (which I don't really know how to read). It's attached here. I was hoping somebody could help me out with making my Mac a little easier and more reliable to work with. Otherwise, I would consider getting a new laptop.
