Frozen content - Unable to resize or move frames

In InDesign, I am unable to modify text box frames and images once I’ve placed them on a sheet and escaped out of a command. When I go back to try to move or resize content, layers become frozen and won’t move or resize. I am able to shift frames when pressing the arrow keys and I’m still able to add text and remove text, but I’m unable to modify or relocate items with mouse.
