Failed to open document error

I’ve been working on a file for days and now that I try to open it to continue I get this error: “Failed to open document
Already tried many from google but still not work
If someone could work on it to get it back, I’d really appreciate it.
File: Wedding dress showroom - Google Drive

Fixed incorrect tag usage.

Purged unused. Looks like a lot of hoarding going on.
