All tool windows disappeared and won't come back

[Brian]

I'm using 2.10.12 Portable and after editing a photo, all of the pointers changed into what looked like a small line in each of the 4 corners. This was for at least the pen, pencil, and eraser. I couldn't get it to change back to a normal pointer. I closed and restarted GIMP and now the enter GUI is gone except the file, edit, etc menu, and none will reappear if selected in the window menu. Any idea what happened?
