Sorry to hear about the trouble. Please ensure that you have the latest version of XD that is 51 and you have the latest build installed for the display drivers as per the manufacturer's website. In case you're on the latest version and still it's crashing, please uninstall XD using the Adobe Cleaner Tool and then re-install XD and check if this solves the issue. If this doesn't work as well, please share a few more details like:
Is it happening every time while creating a new file?
Once the application quits do you get an option to submit a crash report? If yes, please make a note of the crash in the local time-stamp and share Crash Dump and System Logs
With these details handy, I'll escalate this further to the Engineering team.
