Hi Anjineyulu Vuddandam,
Have you recently migrated your app into a newer Studio Pro version?
Either way, have you tried updating the Marketplace modules from your application? I had one scenario where that was the problem and the solution was indeed updating the marketplace modules.
I hope you can solve your issue, best regards!
I never saw this problem, but upgrading to Mendix 9.24 might be worth a try.
I hope this helps.
