The project uses a slightly dated version of .NET framework so you might have a newer version.
During development when we'd run builds windows would pop up asking us to confirm we want to run the program because it might be dangerous. Did you get anything like that when you tried to run the exe?
The requirements for running the game seem to be a 4.x .NET Framework (we used 4.7.2) and OpenAL 1.1 which should be bundled with the game. I would give installing OpenAL 1.1 a shot and see if it helps.
