Can't Launch Rust anymore :(

I am playing rust on my macbook pro so i know its not ideal.But before the most recent update it worked perfectly. I’ve tried everything to get it to work but it just cant get past the load screen. Anyone found a good solution?
Also the launcher that appears before the game has stopped showing up I’m sure i did something dumb but is there a way to get the launcher back?

Try to reinstall it, or if you are using steam verify game files
