A bit more info would help people help you.
At the moment all I have to say is:
“Cool.”
So, if you could supply a bit more information that would be nice. Then I could tell you that your project uses too much data, or that you are not actually logged in to that account so you can't save it.
My advice is:
Download your project before you lose it.

I think the problem is that my game is too big for scratch, It's 277,000 KB and I'm not even close to being done. I wish the scratch team would increase their maximum storage.

There is no limit for project size, but if any individual costume or sound exceeds 10 MB, it won't save.

Are you sure there isn't a block limit, because I have thousands of codes in multiple sprites

The project.json file, which includes blocks, can't exceed 5 MB. Try downloading the project, renaming it so it ends with “.zip” and check the uncompressed size of “project.json” inside it.
