For some reason I am not able to select the vertices/edges/faces on Blender. I also cannot join the objects in Blender. When I try joining them it says "Active object is not a selected mesh," despite the fact that I have both of the meshes highlighted. Here is a gif of what I mean when it won't let me select vertices, and yes I am in vertex select mode. Also, it won't even let me select all of the vertices when I press
A on the keyboard.
