I havent heard this issue before, if you could share your computer specs and also if it works better on your other computer that would be great.

Been having the same issue, awesome softare when it runs though. On my machine the crash is always after I press generate spritesheet and occurs about every 4-5 generations.
It occurs less frequently on my office work computer. My home PC it crashes the standalone version often and that's a 1070ti with AMD Ryzen5 3500, 16GB ram, Windows 10.
Edit: this is with both generators, Modern and Fantasy.
