You have two open faces… You need to close one in order to cap it.

Cap only works on closed planar curves.

In simple terms, draw a single curve between corners and then select the other three edges and create a plane using _PlanarSrf

Once you’ve joined the parts you can cap it.


Or use EdgeSrf on those two edges. Then join the result with your object and use Cap to close it off.

many thanks
