I have made a prefab that also had a canvas. Unity added a Canvas Environment as the parent. Never had an issue until today. For some unknown reason, when I try to edit the prefab, the Canvas Environment is greyed out and not ticked in the inspector, and I am therefore unable to see any of the prefab in edit mode. I am unable to tick it in inspector to activate it.

Any ideas? It has happened to all prefabs that have a Canvas Environment. What have I accidentally done :(

You have disabled the canvas by accident, in the inspector for the canvas click the little box on the left of the name to enable it again.

You can set UI environment through Edit > Project Settings > Editor > UI Environment. A scene asset can be set there. If the set scene contains a Canvas component, it will be used as an Environment for UI prefab edit mode. Go to that scene and make sure Canvas is not disabled there.
