If at first you don’t succeed have a cup of tea.
Airing cupboards are always problematic for door movement, even MDF doors bend because of the difference in temperature between the inside and outside of the cupboard. I tend to try and put some kind of vent in airing cupboards and boiler cupboards just to try and even things out a bit. This is mine, the doors have still moved quite a bit.

Bolts will hold the doors in the correct position but are a pain if you need to access the cupboard regularly.
Any of the solutions mentioned might work but I do think there is always an element of luck involved with airing cupboard doors, especially using real wood.
They’re very nice doors but wouldn’t match the style of doors in the rest of the house. However it does give me an idea. If I can’t make the current doors work then I could try an MDF base and then glue thin (8mm) matching on the front to give the right look. That composite may be a bit more resilient to twisting?
