C1-21 Win 10 - Image Export Incredibly slow

When exporting (via Process Recipes) a single 50MB RAW file to JPG or any format for that matter, when clicking the Process button absolutely nothing happens. After a few more clicks, I see the activity icon spin around. Clicking on it reveals that Process 9 of 13 variants with 14 mins left.

I have left the device for over one hour and still progress is at 9 of 13. All other C1 functions appear to work.

Even after shutdown and restart it still goes on and on. I never had any of this on the same PC device with C1-12, C1-20. I am really disappointed in C1-21.
