Any tips on how to prevent crashing with 2015 Macbook pro with Rhino 7?

here’s a screen shot of my specs

I am new to Rhino 7 (I’m a student) and would love to know if there’s a way for me to prevent it from crashing every 2-3 minutes. I am hardly using rhino, I’m only on wireframe mode and still it crashes.
Are there any lower end settings I can do to prevent it from crashing or should I go to rhino 6 with these specs?

You’re one service release behind on Big Sur, but I don’t think that’s it.
Rhino is never going to run well on an Intel GPU Mac.
