Hello! I have a course that concluded at the beginning of this month and I am not in need of the students grades anymore, however I do need to download the assignments submitted (I had a blank moment and forgot to do it before I submitted grades for my institution)

Normally I would do the 3 dots in the gradebook on the assignment and then "download all submissions" but now when I'm doing it, it acts like it's downloading and does indeed download a zip file, but the zip file is always empty. 

I have tried it on multiple computers, tried logging out and back in again, also showing concluded students, etc. I can access the assignments in the speedgrader but it appears to make me download them individually and that's quite a bit of students. 

Any advice or guidance? Thank you in advance!
