It appears that it's not possible to make a problem where the first move is a pawn taking another pawn en passant.

And It's not possible to castle the king neither.

i have verified your problem with castling, but en passant seems to be possible:

I don't know what I do wrong when i try it.

There is still a small bug. Your problem illustrate it. In your problem, the "En passant" move is illegal because the last black move is obviously not G7-G5 because there is a tower in G7.

oops, forgot about the source square! i've replaced it with a new problem that should be legal.

one thing i forgot to mention about en passant in setup: you have to right-click the square and check the en-passant box to select it for a pawn.
