UI from prefab unresponsive

I have tried several times to take my entire UI into another project, but the elements end up unresponsive or frozen. For example, I cannot click a button, the mouse over doesn’t even work. I have been creating a prefab from the Canvas then exporting it as an asset then loading it into my new project. I’m about to try just individual dialog boxes. I’m sure it’s something i’m doing wrong, any ideas? Thanks.

You missed adding an EventSystem.

It’s not automatically part of the UI hierarchy, you will need to manually create one.

Ah yes, I see. Thank you!
