Do you get any errors when you run the exported version in the console? Does the crash happen at a certain point or at startup?
If it happens at a certain point, I would check the scripts/scenes used at that point to see if there is anything that might cause the issue. Loading resources in code using load/preload without adding res:// to the beginning of the file path can sometimes causes crashes.
Also, this topic may be helpful as a user there was having a similar issue.
