"An error occurred opening file" Can someone help?

[TomasBeckett]

I tried opening a file I was working on just yesterday and I recieved the message "An error occurred opening file" followed by my file location. The file itself still says that it has 1961 KB so all the data is still there, I don't understand why it won't open.

Animate is up to date, all my apps are, I just made sure of that.

Could someone from the adobe support team take a look at the file for me? Or if anyone in the community knows a current day solution to this (not something from 2017) that would be awesome, thank you.

A timeless solution that never gets old is to use the last backup copy of your file (which you have organised yourself to prevent serious data loss).
