Hi there,
I am sorry for the bad experience. I would request you to please generate both the Crash dump and Logs and upload them to a shared location such as Creative Cloud or Dropbox and share the URL with us so that we can investigate the issue. Once the logs are generated, please try the below steps-
1. Uninstall XD using the Cleaner tool
2. Quit Creative Cloud Desktop app and kill all related processes from Task Manager.
3. Delete temp files by going to run(Win+r) then %temp%
4. Delete Adobe XD CC folder from C:\Program Files\Common Files\Adobe
5. Restart the computer and install XD
Let us know if that helps.
Thanks,
Harshika
