How do I open a file with this error message?

Hello, When I try to open a student's c3p file I get this error message: https://nimb.ws/xV7Npv

This is her file https://drive.google.com/file/d/1-uApGQycRwWCbwzjeBrLGyUaFtrlByke/view?usp=sharing

Can anyone tell me what I'm doing wrong or what's wrong with the file?

Thanks!

I'm afraid the file is corrupt. I tried to recover it but it's too badly damaged to be able to recover any meaningful part of the project. Perhaps network or hardware failure corrupted the file in transit. Try retrieving the file a different way from the student's device, or use a backup.
