Hi Neha,

Please check out this question: https://forum.mendix.com/link/questions/103195 

Would that solve it?

If not, can you provide a little more information? Did it work before? What changed since then? Did you restart the computer and did that change anything?

It may help moving your mendix project to a folder outside of you user folder and make sure it is not on a onedrive folder for example. Other tools may interfere with the working of Mendix.

I hope this helps.
