Repeated crashes of Photos app due to signal: Bus error: 10
In general Bus error 10 means that the program has died due to an unhandled SIGBUS signal.

The fault can related to some sort of hardware error (possibly a USB device as per this thread) as it is raised by hardware notifying an operating system about the memory access that the CPU cannot physically address (an invalid address for the address bus).

So if you're using any external device (such as smart phone) to import your photos, try to replace the cable or reboot the device it-self and re-try again. Otherwise please check your SSD/HDD for any hardware faults. 

Also to make sure your Mac is healthy, perform the following tests:


Use coconutBattery app to check your current battery health.
Run Apple Hardware Test.
