File Crashes on Opening - NullPointerException - Alice 3

[wbarnum]

I've had a few students come to me with the issue of Alice 3.25 for Windows crashing immediately upon opening their file with a NullPointerException.

I can't see or manipulate the scene or the code, so I have no way to evaluate what the problem might be.

The only similar posts that I can find deal with Alice 2, so I don't know if the cause is related.

I have attached three samples of files that display this behavior.

If anyone else experiences this problem, I would be interested to hear about it.
