Command enter does not work


Hello all - I have been using sublime text for months and had no issue. Today, I no longer can send code from sublime text to my terminal. Generally, I open the terminal, go to the appropriate folder, start R. And then within a file i can highlight code and hit enter and it will execute in the terminal. Any ideas why this no longer works?
I have mac 11.5, using sublime 4. thx!
