Does any one has this same issue & resolved with this November CU ? or if any other solution is there Please kindly let me know.

Hi Kumar,

I'd suggest to install the CU on a dev or test tenant and see if it helps. Otherwise try to look at the ULS log to see if you can have more details on the error.
