Well, the saw is supposed to be invisible, and the wood is supposed to disappear I believe. So I can only assume this is some sort of user error. (before you jump to conclusions, I am NOT calling you stupid)
But.. One other person said he has the same problem, I think.
Ok, try this. Around you you might find explosives. Pressurized gas canisters, to be more precise. Try making them explode near the door. Hopefully, it just might throw it open
(although I'm not entirely sure if that's coded in)
Otherwise try finding rocks or whatever and throwing them at the door.
Let me sum it up: the door killed your wife.
(PS IIRC you should grab the door on the right side)
Edit: won't work.

Still, you should try it!
