Bitcoin core keeps crashing while loading

I updated bitcoin core recently, it worked perfectly fine until yesterday when I came home I found a crash notice, I tried to reopen it, and it keeps crashing with this message, I’m on mac

What is going on, I don’t want to loose my coin 🙁

The error message is too long for here so I pasted it
