Hi Callum, thanks for the response! The format for export is JPEG @100%. I edit in ROM RGB colorspace and have it converted to sRGB for my website. I checked the crash report folder and there are a few in there from other crashes I have da over the last month, but since this event was not a crash, there was no report.
Incidentally, in ensuring I knew what I was exporting at, I ran the export again but let it export into the same folder I have all my working files in. It exported without issue, but when I tried to run it again in my original folder it would not export. I have checked the properties of the folder and everything looks fine. I don't know what in the world is going on. If we can fix it, awesome, if not at least I know there is a workaround.
I also tried opening AP in cmd to see if it showed information as the app was running as apps do in Linux so I could tell you what it is saying. If there is anything else I can do on my end to help, please let me know.
