'Chrome Extension No manifest found in package

Currently trying to add a new extension via the Chrome developer dashboard but getting the below error when I try to upload the zipped folder.

No manifest found in package. Please make sure to put manifest.json at the root directory of the zip package.

This is what's inside the zipped folder, which as you can see, has the manifest in it's root.

The manifest is v3 and everything works fine unpacked in the extensions developer mode when I'm testing it.

Any ideas what I'm missing here?

It turns out it was as simple as the name of the manifest being Manifest and not manifest... the capitalised M made all the difference...

there's a day of my life I'm not getting back.
