[Solved] Saved project as a Project Folder and now won't open

I keep getting a

"Failed to open Project. Check it is a valid Construct 3 folder project"

but nothing has changed that I know of.

All the project files are there so I'm not sure what it is giving it a problem. How do I even remedy this?

I figured it out.

I had renamed pngs from the /images folder (the whole point in doing a project file as I want to just replace those images rather than reimport everything.)

anyways, the file naming convention is a bit different than the animation name.

I wish there was a better Popup message!
