Hello 🙂 After reporting the bug on discord, I was invited to add a topic on the forum. So here's the thing, I just can tell that i upgraded the difficulty after the stage 1, i had the opportunity to beat the first boss of the run and i shoot my last bullet with my slicer on the very low hp CEO. After that, the game crashed and closed immediately. It was the first time the game crashed for any reason, i hope this report can helps the dev team ! Have a nice day !
