''Add'' options problems with blueprints

Hi, im starting to use UE 5 but i have been struggling in some aspects. Firstly, after creating a blueprint class for a character, i try to use the ‘‘add’’ tool at the left to add a Cube or whatever, but idk why i lost most of the options of this tool and i don’t know how to recover them because without them i can’t do barely nothing. I’m adding a photo of what is showed to me instead all the options.
The other problem i have is that after creating that blueprint class, firstly it opened a menu but if you close that menu when you open the blueprint class it doesn’t show the same menu and i want to know how to change it so i can see the menu with the viewport and everything again. I’m probably having those problems because i’m new with the engine and in gamedeveloping but i would be very grateful if you help me.

try Window → Load Layout → Default Editor Layout, that should reset all viewports and window panels
