Sorry to hear about your difficulties. Typically when you select an element, you should get a box around it with a bar and some additional options including replace. I try these and see if they help: - Try clicking the blank photo in the canvas to see if you can select it
- Can you add another photo over the top of this one?
- Does creating a duplicate of the project and working in that instance make any difference? - Try clearing the browser cache - https://adobe.ly/3MPJpg1
