I was attempting to print a file, but the program would crash immediately on Windows without providing a stacktrace.
I decided to run this on my Mac, which generally provides a stack trace upon crashing, which it did:

The above stacktrace has been stripped for privacy reasons, but the reproduction process:
1. Export an image using Lightroom.
2. Attempt to use depth information.
3. Program should crash.
The program will print fine without using depth information. I am not sure what specifically causes this, as this is an entirely clean installation. I would send the offending file, but it contains personal information that I am not willing to share.
I originally suspected it to be related to metadata, but I attempted a clean re-export of the offending file using the Preview tool on Mac, which still caused the crash.
