Hello, I may be also able to help you too.
However, we would need you to provide us details. If you're using smapi (which i assume) to run the game, could u please see if you're having any error (red-texts) on your smapi and post it here
https://smapi.io/log (instructions are posted there) then post the link here after uploading your log :)
As
@liquidkitten mentioned, I would also be interested to know how and when it crashes such as if you go to town, does it crash, etc...
