Problem with 2015 MacBook Air

I was in a call with my friends and unexpectedly my MacBook crashed and I had to restart it. So I did restart it and it opened like usual I had to type in my password and everything, then the bar was loading and it kept stopping at the middle I tried resetting it again tried using first aid, nothing worked (I even had to keep it open for 3 days to see if it would load further.) I’m very worried, is there a way to fix this?
