Sorry for the cause. Such dialog box appears when XD experience crash.
Is it happening continously. If yes , you can click on top blue statement " Enviar informe" it will open the location where crash dump file is stored and provide us that dump to investigate. I may need more information to dig into the issue like
1. What all steps you did which led to crash
2. After how long you started XD, like system was on sleep mode or you were working in background.
3. OS and Xd version
4. What is the reproducing rate
We are sorry for the frustration. In addition to what our expert has asked, I would also request you to please try the steps mentioned in this post: https://community.adobe.com/t5/adobe-xd/troubleshooting-adobe-xd-crashes-white-screen-on-launch-on-w...
