The folder was in OneDrive, was 116 gb, had 1419 folders and 38,439 files. There were 2 crash logs and I submitted both of them. I had tried to delete the folder once and nothing happened, then I tried again and it crashed.
The ID for the submission is 540.
Looks like a bug in something that has installed a Copy Hook, not any code that's part of Opus itself:
You can get a list of copy hooks, and block any you don't need, via Preferences / Miscellaneous / Shell Extensions (then select Copy Hook as the category). Rebooting afterwards may be worthwhile, in case the problem has already happened by loading the DLL in question.
(Copy Hooks are run when deleting files via the recycle bin, as well as when actually copying files.)
Thanks Leo. There's only 3 copyhooks that show up in Shell Extensions:
I need Dropbox and obviously the Windows OS. Any other suggestions? My inclination is to reboot and see if it happens again.
The things the copy hooks do are often not essential, even if you use other parts of the same thing, although I don't know in this particular case.
(Sometimes disabling one type of component also disables others, e.g. context menu extensions, if they're implemented by the same component.)
Updating Dropbox would be my first action if it seemed to be involved in a crash.
