unable to edit in edit mode I was following a tutorial in blender on basic stuff like nodes, texturing and what not, i tried to hide one of the meshes when I was in edit mode and it went grey. I'm no longer able to edit nor select the mesh. i'm a beginner so you may have to go in depth on how to fix the issue.
A screenshot will help to give a clear answer!

Try going to object mode again and going to edit mode. if you are not able to select the vertices or faces means that the object is a different from what you are trying to edit.
