Have you tried ticking View>Show Bounding Box?
That was it! I had not unticked it, but I must have done the keystrokes that turned them off by mistake.
You have saved my deadline. Thank you so, so much!

You are welcome, Marcy.
It is quite easy to accidentally make the keystrokes, but the Bounding Box hiding may be caused by a preference corruption.
So if other strangenesses appear, you may try to Ctrl/Cmd+Alt/Option+Shift during startup or to Move the folder to get unstuck.
Among others, the Bounding Box issue is mentioned more detailed in When things disappear or become unavailable
THANK YOU THANK YOU THANK YOU!
I couldn't figure out what I did. Thank you for helping me fix it.
