Hi @BishwaR ,

 

The information you provided cannot provide more opinions, but a similar solution is solved by updating to the latest version of the desktop, refer to the following and you can make a try:

Solved: An unexpected error occurred (file 'xlattrmap.cpp'... - Microsoft Power BI Community


If the problem is still not resolved, can you provide more information about the data model or dax code, I will answer you as soon as possible. Looking forward to your reply.

Best Regards,
Henry

Hey @BishwaR ,

 

that's somehow hard to say. How does your DAX code look like and how the tables and data model?

 
If you need any help please let me know.
If I answered your question I would be happy if you could mark my post as a solution ✔️ and give it a thumbs up 👍
 
Best regards
Denis
