I have the same issue on the latest indesign. It just won't copy, even thought he little double cursor appears. Also, holding down the shift key at the same time, won't keep things aligned. Non of this works. Ugh.... !!!! Tried to screen record this, but the double cursor won't show up on the screen video... so it looks like I am just moving it around. So frustrating that the keyboard input isn't being read. Also the space bar isn't letting me move the condiment around. Definitely something off here.
