Lightburn Not Responding on Mac

I am running lightburn with my Mira 7. It will work fine then all of a sudden Not Respond. I restart both computer and machine. Sometimes it works sometimes not. It’s busy season and of course it’s happeneing now. Not to mention my bridge stopped working months ago and I have no idea how to re program it. The tutorial they sent was like looking at. different language to me.

I actually cant even open the program with it going to NOT RESPONDING,
