I've never worked on anything gaming related, but the bigger cross-platform games certainly have crashes. I can't even tell you how many times Fallout 4 has crashed for me (likely hundreds). I obviously don't know if rust could help, but it's not unreasonable to think it might.

Games are large codebases often not replacing the OS standard calls (which is where replacing C with Rust becomes problematic as you start breaking the standard library) that would benefit insanely from the safeties and default saneness Rust gives developers.

Any time you work in a large team in a corporate environment you want a language that lets you stab yourself in the foot as little as possible.
