I didn't got a crash on Linux/Wayland. And I didn't tested on MacOS or Windows.

What's your device envionment?

Could you please submit a GitHub issue to neomacs? (better with a minimal reproducible script and log `RUST_LOG=INFO ./neomacs` can output the debug log)

It's a highly experimental thing someone decided to mess around with, without any prior design discussion with any Emacs core devs. It's like a forty-minute-old baby and you're asking it to parallel park without crashing. What's your point here, I don't get it?

GNU/Emacs is incredibly stable. It's one of the most reliable pieces I've ever had; I sometimes run it for months without ever restarting. Which I can't say about pretty much any app on my system. Including the system itself.
