Nope. It hasn't crashed on me so far. I use it every day for commuting and it's worked fine (am on BUKG)
It's janky and much more laggy on A12 as compared to A11, especially when moving the screen around and having a media app playing, but except for that stutteriness, it does the job. Doesn't crash. Not so far, at least.
Do you have a Hex-Theme enabled? If yes, you need to disable it, to make Maps working again. But be aware, if you disable your Theme one OneUI 4, you can't apply it again (it will reset after 10 Minutes).
