Have you tried with smaller batches? Can you see any resource getting overloaded, e.g. RAM? Use activity monitor while converting. Does you Mac run off mains or battery power when you convert?
I’ve tried to add 1200 images to DPR and that made it quit unexpectedly - and the issue can be reproduced. I see no exceptional load and memory usage though.
Tested with DPR 2.0.2.1 on macOS 12.4 on iMac 2019
DPR loaded 280 images without issues - looks like DPR can’t handle more than ??? images.
→ Until this bug is fixed, you’d better work with smaller batches.
