Lightroom is constantly crashing my Macbook Pro—not just freezing the program—I need advice..

When the computer crashes (as opposed to a piece of software crashing but the computer still runs other software properly), this is almost always a bad/corrupted/out-of-date driver, or a hardware malfunction. So, you need to re-install all of your drivers, and verify that all hardware is working properly, including the cooling system. I'm not sure what "maintenance utilities" you ran, but sometimes those don't actually check for certain types of problems.

Anyway, it's not only Lightroom that can be running when this happens. It may be true that Lightroom is the only software ON YOUR COMPUTER that is running when this happens, but if you read the Apple forums, this happens when many other software products are running. So it is not just Lightroom.

The helpful screenshots show Mac OS crashing when it accesses the graphics processor (GPU) on your relatively old 2013 Macbook (which is ancient in Apple years). Try disabling the GPU by setting the LR option Preferences > Peformance > Use Graphics Processor to Off.

Unless you have a 4K display or larger, the GPU usually provides little benefit.
