Pop up for selecting masks generative fill etc disappeared

Hi everyone,

I'm a newbie and can't figure out why a pop-up toolbar has stopped popping up. Normally when i place an embedded image onto my image, a pop-up toolbar with a generative fill button, select, mask etc is visable below the image selected. It randomly stopped popping up after editing a few images. I'm sure I've just pressed accidental short cut or something which must have disabled it. Can someone please help me to figure out how to get it back on? It is extremely useful. I find that it selects the objects so much better than the standard wizard or object selection tool. No idea why. 

Adobe Photoshop Version: 25.9.0 20240516.r.573 296f739 x64

Operating System: Windows 11 64-bit
Version: 11 or greater 10.0.22631.3672

Thanks in advance
