Sorry to hear about the trouble. Could you please share a few more details like:
The version of Adobe XD and the Operating System.
Is there a pattern when it crashes? Is there any specific workflow that causes the app to crash?
Is this happening while working on a specific file? If yes, would you mind sharing the file with us so that we can test this? If yes, please add the file to cloud storage and you can share the link either here or you can send a private message by clicking on my name.
