Adding to what Atul is saying, bigyanpra can you also share the AdobeXD.log (you can paste this in Explorer to get to it: %USERPROFILE%\AppData\Local\Packages\Adobe.CC.XD_adky2gkssdxte\LocalState )
For sharing, I think you can use something like pastebin (or another service of your choice) and link it here.
Do you get this error with any specific file, or is it with all the files? I would also like to know the version of Adobe XD and OS build that you are using.
