Bridge CS6 often crashes working with DNG files from Canon G7X Mk II

I mainly shoot with two different cameras and end up with two different types of files- a Nikon D800, which gives me NEF files, and a Canon G7X Mark II, which gives me CR2 files. I import files directly from cards into Lightroom (6.10.1), but when they are from the Canon, I immediately convert them into DNG files. I have done this workflow for years from older DSLR Nikon & Canon small cameras with no problems.

Once I do my quick editing to get rid of bad images and renumber images, I save changes to the raw/DNG files, then open that folder in Bridge CS6 (5.0.2.4). I click on one or more files at a time to open them in the ACR window, make adjustments, then click Done. Generally I do not mix NEF and DNG files when doing this- one or the other. Sometimes Bridge saves just fine, other times...I get the progress bar, sometimes with spinning beach ball, then Bridge crashes, and I loose my edits. I restart Bridge, work for a while, then it crashes again. Occasionally it happens with the larger NEF files, but mostly happens with smaller DNG files.

I have tried restarting the iMac (OS 10.11.6), tried clearing cache in Bridge, but it’s still crashing. Sometimes I am working on two files, sometimes a lot. And again, sometimes Bridge works fine, I can open 10, 20 files at once to make a global change in settings, and Bridge saves them all with no problems, yet other times, even two files will crash it. Bridge writes changes into dng or xmp files until it crashes, so sometimes some of my work is saved, other times it crashes right away. It is just about always the DNG files that crash Bridge, as if Bridge was able to write/make changes to those files much quicker/easier. Which seemingly is counter intuitive- smaller DNG files crash Bridge more than larger, Nikon files...

This has been happening ever since I got that Canon camera. I have no problem opening those DNG files into Photoshop (13.0.6) via ACR window, they always open fine with adjustments, and never crash Photoshop. Changes made in ACR window are always saved fine as well. I thought the whole point of DNG files is that they are not proprietary, and as an open source file, they should be able to be worked with many applications (especially Adobe ones).

Any suggestions or thoughts appreciated.
