Getting Access denied Error message on personal info update pages via ESs and blank pages on change

Summary:

Content (required):

We consumed a maintenance bundle recently and after this update for our custom roles we are getting Access denied Error message for Employees via ESS pages and our HR roles are getting blank pages on Employment info, compensation info, change assignment and local and Global transfer pages... Interestingly, Element entries, Calculation entries are not impacted.

We have submitted SR to Oracle and they tried the options of regenerating the roles, bouncing the servers, checking the priveleges, untagging and tagging the priveleges back. But nothing worked so far.

Have anyone of you faced this situation ? If so could you share how this was resolved other than the ways we have tried above.
