If it's 0.5.3, I've had reports that it crashes more in Dub Mode than previous versions. It's being investigated and will hopefully be more stable in 0.5.4. Many peoples' PCs play it with no issue, so it's very confusing why it's causing issues for others
if possible in godot, i would recommend adding crash logs for people to post so you can see what's causing issues. it could just be on lower-end laptops, but i haven't been able to play through a single dub mode game without it crashing regardless of mode so far
