Student 'lost' code

I have a student who was working on Unit 4 Lesson 8 Level 3 in AP CSP and she ‘lost’ her code. She says version history is blank. When I access her account as the teacher, I see a blank screen also (except for 1 comment on line 1). Is there a way as a teacher to retrieve student’s previous versions of code? thank you!

I don’t think the teacher would be able to do this. I would ask the student to write to indicating the lesson and level where this happened. Hopefully, staff will be able to retrieve it. They are pretty good at responding promptly.
