@danikuci1 How many files were you trying to move?

Also please fill in the rest of the report template, especially the Environment data

danikuci1 commented 2 years ago

It was maybe 20 or 30 files in a folder of maybe 15K files total.

Apologies as I had thought the rest of the environment info would be copied with the crash report. Will retrieve and add.
