The menu of develop options was on the right of the screen. It has now gone.
I don't use photo editing much so was surprised to find in the develop module that the menu of tools and adjustments which used to be on the right of the image is no longer there.
I can't find any obvious reason why or how to get it back in any menu inside the programme or in help.
The only thing which looked promising was f4 but on my iMac that just brings up programme tiles in Mac OS.
