Hi Narendra,
Thanks for posting the query here.
Could you please first use the browser back button and then click the application to retry as instructed in the error message? You may also try a different browser or InPrivate mode?
If the issue still occurs, please click TECHNICAL DETAILS to collect the information and involve your site collection admin on this thread and share with us the application information with us.
Regards,
Tina
