This is a bit odd. My power went out for a few minutes while I was working on an AppGameKit project. Now, whenever I try to launch AppGameKit it immediately crashes with an "AGK.exe has stopped working" error message. I've tried verifying the install integrity from Steam as well as uninstalling and reinstalling AGK. Same results. Any ideas? Everything else seems to be working normally. I'm on Windows 10 Home x64.
[EDIT] Fixed it. It had to do with AppGameKit trying to re-open the project on launch. Something got corrupted I guess. I renamed the folder that contains the project and that seems to have solved it.
