Photoshop CC crashes on save when using High Sierra

I am using an iMac 21.5 inch 2.9 GHz Intel Core i5 processor 16 GB memory

macOS High Sierra 10.13.1

I organize my photos in iPhoto. For editing I use Photoshop CC. I have these versions installed: Photoshop CC 2015, 2015.5, and 2018.

My problem is that no matter which version of Photoshop CC I use, it crashes every time I've finished editing a photo and click save. Just clicking save causes Photoshop to crash and I'm back to square one with the original photo with no edits.

I have contacted apple support but I got lost in the instructions of creating a new user on my computer (test) and could never get back to the support person. I also tried adobe support with no luck.

Please provide a fix to this problem. I have seen many compatibility issues with Photoshop CC and High Sierra mentioned online but none of them has involved saving and crashing. I wish I had never upgraded.

Thanks for any help to solve the problem. I'm hoping to find something soon because Christmas is right around the corner and I'm wanting to work with lots of photos. As of now, I'm in a standstill.
