So, I have this big animation I have been working on for a while now. Its about 8 mins long and has a lot of work put into it. It was working just fine yesterday until I opened it today. Every time I tried to open the project it would just say a fatal error has occurred. Not even my backups are working and now I am confused on what to do. I don't have the motivation to start a whole new project as this one already took a long time. Please help.
(Btw there are other projects I have that are shorter, but files are even bigger then the project I'm trying to open and work just fine)
